DETAILED DESCRIPTION

The present disclosure provides examples of an electronic system assembly comprising a plurality of circuit boards arranged in a geometric shape defining a cavity containing a plurality of electronic components distributed over surfaces of a first set of the plurality of circuit boards. The plurality of electronic components is configured as an electronic system comprising a plurality of electronic subsystems distributed over the first set of circuit boards. The plurality of electronic components is electrically coupled to a set of connectors provided on a second set of the circuit boards.


The term “set,” as used herein (e.g., a set of keys), refers to a non-empty collection of members. The phrase “coupled to,” as used herein and unless otherwise indicated by the context of the usage, means that a first circuit element is coupled to a second circuit element, with or without intervening elements therebetween.



FIG. 1 illustrates a first perspective view of an electronic system assembly 100 according to one or more embodiments. The assembly 100 includes a plurality of sidewalls 102 extending along a first dimension between a first end 104 and a second end 106 opposite to the first end 104. The assembly 100 includes a first surface 108 provided at the first end 104. A set of first connectors 110 are provided on or extend from the first surface 108.


The assembly includes a plurality of attachment means 112 that extend through apertures in the sidewalls 102 and the first surface 108 to retain the assembly 100 together. The attachment means 112 are, in at least some embodiments, fasteners, screws, or bolts that engage with a support structure, as discussed herein. However, other attachment means are considered as being within the scope of the present disclosure. Non-limiting examples of such attachment means include dowels, adhesives, rivets, pins, welds, soldering, and brazing.



FIG. 2 illustrates a perspective view of an electronic system assembly 100 according to one or more embodiments. The perspective view in FIG. 2 is of the second end 106 of the assembly 100. The second end 106 includes a second connector 202 provided on or extending from a second surface 204 of the assembly 100 opposite to a first surface at the first end 104 thereof.



FIG. 3 illustrates an exploded view of the electronic system assembly 100 according to one or more embodiments. The assembly 100 includes a plurality of first boards 302-1, 302-2, 302-3, 302-4 (collectively “first boards 302”) on which the sidewalls 102 are provided. Each of the first boards 302 includes a set of electronic components 304 provided on a surface 305 opposite to the sidewalls 102. The first boards 302 each have substantially similar size and shape to each other.


The assembly 100 also includes a second board 306 provided at the first end 104 of the assembly 100 and includes a third board 308 provided at the second end 106 of the assembly 100 opposite to the first end 104. The second board 306 has a set of third connectors 310 provided on or projecting from a surface opposite to the first surface 108 thereof. Each of the set of third connectors 310 are electrically coupled to a corresponding connector of a set of first connectors 110 via one or more conductors extending through the thickness of the second board 306. The third board 308 has a set of fourth connectors 312 provided on or projecting from a surface 314 of the third board 308 opposing the second board 306.


The assembly 100, in some embodiments, includes a support structure 316. When the assembly 100 is assembled, the support structure 316 is located in a cavity 318 defined by the first boards 302, the second board 306, and the third board 308. In some embodiments, the support structure 316 includes a plurality of apertures 320 sized and shaped to receive the attachment means 112 discussed with respect to FIG. 1 and elsewhere herein. When the assembly 100 is assembled, the attachment means 112 extend through apertures 320 in the first boards 302, the second board 306, or the third board 308, and engage with the apertures 320, thereby securing the assembly 100 together.


When the electronic system assembly 100 is assembled, the first boards 302, the second board 306, and the third board 308 constitute a cuboid shape having six sides. In some embodiments, the electronic system assembly 100 has an elongated cuboid shape in which side edges 322 of the first boards 302 are longer than edges 324 of the first boards 302 at the first end 104 and/or edges 326 of the first boards 302 at the second end 106. In some embodiments, the electronic system assembly 100 may have a cuboid shape in which the side edges 322 of the first boards 302 are approximately equal to the edges 324 of the first boards 302 at the first end 104 and the edges 326 of the first boards 302 at the second end 106. Those of ordinary skill in the art will understand that cuboid geometries other than symmetrical cuboid shapes are within the scope of the present disclosure.


When the electronic system assembly is assembled, the third connectors 310 interface with contacts, traces, or pins of the first boards 302 at or near the edges 324. The interface of the third connectors 310 with the contacts, traces, or pins of the first boards 302 electrically couples the first connectors 110 with the electronic components 304. Also, when the assembly 100 is assembled, the fourth connectors 312 interface with contacts, traces, or pins of the first boards 302 at or near the edges 326. The interface of the fourth connectors 312 with the contacts, traces, or pins of the first boards 302 electrically couples the second connector 202 (see FIG. 2; see also FIG. 5 infra) with the electronic components 304.


When the electronic system 100 is assembled, the plurality of electronic components 304 are contained within the cavity 318. As a result, if any of the electronic components 304 become dislodged due to shock (e.g., sudden deceleration) or vibrational load, the dislodged components remain within the cavity 318 and therefore will not damage any equipment surrounding the electronic system assembly 100.


In some embodiments, one or more conductors are exposed on the side edges 322 and/or surfaces 308 of the first boards 302. The exposed conductor may be coupled to an electrical plane within the first boards 302. When the electronic system assembly 100 is assembled, the exposed conductor(s) may contact the support structure 316, thereby commonly coupling electrical planes in the first boards 302 together. By way of non-limiting example, the exposed conductors may be part of or electrically coupled to a ground plane of the first boards 302. When the electronic system assembly 100 is assembled in such a configuration, the ground planes of the first boards 302 are coupled together via the support structure 316 to provide a common ground.


Features of the electronic system assembly 100 may vary in different embodiments. A shape of the second board 306 and the third board 308 corresponds to a number of the first boards 302. The second board 306 and the third board 308 have a rectangular shape corresponding to the four first boards 302 illustrates and described in FIG. 3. As another non-limiting example, for an electronic system assembly 100 having six of the first boards 302, the second board 306 and the third board 308 would have a hexagonal shape. Those skilled in the art will appreciate that the electronic system assembly 100 may have a different number of first boards 302 depending, e.g., on a number of outputs desired.



FIG. 4 illustrates a perspective view of the second board 306 of an electronic system assembly according to one or more embodiments. The plurality of first connectors 110-1, 110-2, 110-3, 110-4 (collectively “first connectors 110”) are provided on or project from the first surface 108 of the second board 306. Each of the first connectors 110 includes a plurality of receptacles 402 for receiving a pin or conductor of another apparatus or system with which the electronic system assembly 100 is configured to integrate.


A first pair of the first connectors 110 (e.g., first connectors 110-1 and 110-2) have a first orientation and a second pair of the first connectors (e.g., first connectors 110-3 and 110-4) have a second orientation different than the first orientation. The first and second orientations may correspond with an adjacent edge 404 of the second board 306. In some embodiments, the second board 306 may have only a single connector 110 provided on or protruding from the first surface 108. In some embodiments, the second board 306 may include a different number of the first connectors 110-for example, the second board 306 may have two first connectors 110 instead of the four first connectors 110 shown. The second board 306 includes a plurality of the apertures 320 extending entirely through a thickness of the second board 306.



FIG. 5 illustrates a perspective view of the third board 308 of the electronic system assembly 100 according to one or more embodiments.

The third board 308 includes a set of the apertures 320 extending through a thickness thereof. The apertures 320 are each sized and shaped to engage with a corresponding attachment means of the apparatus or system to which the electronic system assembly is configured to integrate. For instance, the apertures 320 may have threading for engaging with corresponding threading of a screw or bolt. In some embodiments, the third board 306 may include a mechanism other than the apertures 320 for attaching the assembly 100 to another apparatus or system.


The third board 308 also includes a set of mounting receptacles 504 extending into or through a thickness of the third board 308. The mounting receptacles 504 may be threaded or otherwise adapted to engage with a corresponding fastener (e.g., bolt, screw, pin) of a device or system with which the electronic system assembly described herein is configured to operate. In some embodiments, the mounting receptacles 504 may instead be a male attachment means projecting from the first surface 204 and adapted to engage with a corresponding female attachment means of a device or system with which the electronic system assembly described herein is configured to operate.


The third board 308 further includes a plurality of conductor sets 506 each comprising a plurality of conductors 508. The conductors 508 include a first portion exposed on or extending from the surface 314 of the third board 308 opposite to the first surface 204. In some embodiments, each of the conductors 508 include a second portion exposed on or extending from the first surface 204 and extend entirely through a thickness of the third board 308 to the second surface 314. Each of the conductors 508 is electrically coupled to one or more conductors in the receptacles 502, e.g., via one or more conductive layers in the third board 308.



FIG. 6 shows a perspective view of one of the first boards 302 of the electronic system assembly 100 according to one or more embodiments. The first boards 302 each include the surface 305 on which the set of electronic components 304 are disposed. The set of electronic components 304 may include one or more electronic devices 602 that are configured to perform a set of operations. For instance, the one or more electronic devices 602 may include a processor, an integrated circuit, an Application Specific Integrated Circuit, a system-on-chip, or a Field Programmable Gate Array, by way of non-limiting example. As a specific non-limiting example, the electronic device 604 may include a power converter configured to convert input power into another type or level of power. In some embodiments, the first boards 302 include a plurality of the apertures 320 extending through the first board 302 in a thickness direction thereof.



FIG. 7 illustrates a perspective view of an example support structure 316 of an electronic system assembly according to one or more embodiments. In some embodiments, the support structure 316 has a cuboid shape corresponding to shapes of the first boards 302, the second board 306, and the third board 308. The support structure 316 includes a central column 702 extending along a first dimension (e.g., a vertical dimension), a plurality of arms 704 extending outwardly from the central column 702, and a plurality of rails 706 provided at distal ends of the arms 704. When the electronic system assembly is assembled, each of the plurality of first boards 302 (see FIG. 3) is supported by a pair of rails of the plurality of rails 706. In some embodiments, a single rail of the plurality of rails 706 supports two of the first boards 302.


In some embodiments, each of the rails 706 includes a plurality of apertures 708 sized and shaped to receive the attachment means 112, as described with respect to FIG. 1 and elsewhere herein. Each of the rails 706 includes a first set of the apertures 708 located at a first end 710 and a second set of the apertures 708 located at a second end 712 opposite to the first end 710. A first set of the apertures 708 are sized and located to correspond with the apertures 320 in the first boards 302.


In some embodiments, the support structure 316 is a monolithically formed structure. In some embodiments, the central column 702 is composed of a thermally conductive material, such as copper, aluminum, or graphite. In some embodiments, the support structure 316 may be generated using a three-dimensional printer. In some embodiments, the support structure includes a plurality of pillars 714 projecting outwardly from the central column 702. Each of the pillars 714 is located between adjacent rails of the plurality of rails 706 on each side of the central column 702. The pillars 714 are each sized and shaped to be adjacent to or contact with one or more of the electronic components 304 on each of the first boards 302.


When the electronic system assembly 100 is assembled and is in operation, one or more of the pillars 314 absorb heat from one or more of the electronic components 304. The heat is conducted through the central column 702 to effectuate a more even thermal distribution on or from the electronic system assembly. When the electronic system assembly is assembled, the support structure 316 also provides structural rigidity and support for the first boards 302, the second board 306, and the third board 308. As discussed herein, When the electronic system assembly is assembled, the support structure 316 may commonly couple one or more planes of the first boards 302.



FIG. 8 shows an example block diagram 800 of an electronic system 802 included in an electronic system assembly according to one or more embodiments. The electronic system 802 includes a plurality of electronic subsystems 804-1, 804-2, 804-3, and 804-4 (collectively “subsystems 804”).

FIG. 10 shows an example block diagram 1000 of an electronic system 1002 included in an electronic system assembly according to one or more embodiments. Various features of the block diagram 1000 are substantially similar to features depicted in and described with respect to the block diagram 800, so further description and illustration thereof is omitted. The electronic system 1002 includes a plurality of electronic subsystems 1004-1, 1004-2, 1004-3, and 1004-4 (collectively “subsystems 1004”). Each of the subsystems 1004 corresponds a set of electronic components 304 on one of the four first boards 302 comprising an electronic system assembly described herein.


In the block diagram 1000, the electronic system 1002 has two or more subsystems 1004 connected in series with each other. For instance, The subsystems 1004-1 and 1004-2 are connected in series and the subsystems 1004-3 and 1004-4 are connected in series. More particularly, an output 1006-1 of the subsystem 1004-1 is connected as an input to the subsystem 1004-2. An output 1006-2 of the subsystem 1004-2 is connected to a load 1008-1. An output 1006-3 of the subsystem 1006-3 is connected as an input to the subsystem 1004-4. An output 1006-4 of the subsystem 1004-4 is connected to a load 1008-2.


An input 1010-1 is connected to an input terminal of the subsystem 1004-1 and an input 1010-2 is connected to an input terminal of the subsystem 1004-2. In some embodiments, an enable signal 1012-1 is connected to enable terminals of the subsystems 1004-1 and 1004-2. An enable signal 1012-2 is connected to enable terminals of the subsystems 1004-3 and 1004-4. The output 1006-1 is generated based at least in part on the input 1010-1. The subsystem 1004-2 generates the output 1006-2 based at least in part on the output 1006-1. The output 1006-3 is generated based at least in part on the input 1010-2. The subsystem 1004-4 generates the output 1006-4 based at least in part on the output 1006-3. One or more of the subsystems 1004 may receive additional inputs (e.g., from a system 1014 external to the electronic system 1002) adjusting operational parameters thereof.


The subsystems 1004-1 and 1004-3 may have different functionality than the subsystems 1004-2 and 1004-4. For instance, the electronic system 1002 may be configured to convert a DC voltage input 1016 to two AC voltage outputs 1006-2 and 1006-4. The subsystems 1004-1 and 1004-3 may be DC-DC converters comprising, e.g., a boost converter, an inverter circuit, and a rectifier circuit that collectively convert the DC voltage input 1016 having a first voltage level to DC voltage outputs 1006-1 and 1006-3 having a second voltage level. The subsystems 1004-2 and 1004-4 may be DC-AC converters comprising an inverter circuit and an output filter that are collectively configured to convert the DC voltage outputs 1006-1 and 1006-3 to AC voltage outputs 1006-2 and 1006-4, respectively. In some embodiments, the subsystem 1004-4 may include a phase shifter configured to shift a phase of the AC voltage output 1006-4 by a defined amount relative to the AC voltage output 1006-2.


In some embodiments, the electronic system may be a multi-stage device, such as a variable AC-DC power supply. FIG. 11 shows a block diagram 1100 that includes an electronic system 1102 comprising subsystems 1104-1, 1104-2, 1104-3, and 1104-4. The subsystem 1104-1 includes a transformer having an N:1 or 1:N winding ratio, a bridge rectifier, and filtering components (e.g., capacitors). An input of the subsystem 1104-1 may be connected to an AC input voltage 1106, such as a 240V 60 Hz AC source. The subsystem 1104-1 may convert the AC input voltage to a DC voltage 1108-1 based on the transformer winding ratio.


The subsystem 1104-4 may be a Buck converter circuit configured to convert the DC voltage 1108-1 to a DC output voltage 1108-4 having a different voltage level than the DC voltage 1108-1. The subsystem 1104-2 may include an output scaling stage (e.g., including a voltage divider) and a differential amplifier stage. The subsystem 1104-2 is connected to receive an input 1110-1, which may be a selectively adjustable reference signal or a selectively adjustable circuit component, such as a potentiometer. In some embodiments, the input 1110-1 may be set at a defined voltage value based on values of one or more resistors. The input 1110-1 is connected to a first input terminal of a differential amplifier circuit and the output scaling stage is connected to a second input terminal of the differential amplifier circuit. The differential amplifier circuit generates a DC output 1108-2 having a gain based on a difference between the input 1110-1 and a signal from the output scaling stage.


The subsystem 1104-3 includes a comparator circuit that is coupled to receive an input 1110-2 that is, in some embodiments, a periodic signal, such as a triangle wave. The comparator circuit generates a pulse-width-modulated (PWM) signal 1108-3 based on a comparison between the input 1110-2 and the DC output 1108-2. The PWM signal 1108-3 is coupled to an input of the Buck converter circuit of the subsystem 1104-4. The subsystem 1104-4 generates a DC output voltage 1108-4 based on the PWM signal 1108-3. The DC output voltage 1108-4 is fed back to the output scaling circuit in the subsystem 1104-2 and a pulse width of the PWM signal 1108-3 is adjusted based on the feedback.


The electronic system 1102 may be configured to recharge a load 1112, such as a battery in an electric vehicle. The electronic system 1102 and parameters of inputs thereto may be adjusted to charge batteries, e.g., based on their state of charge or other characteristics particular to the battery, such as a target resting voltage. Those skilled in the art will appreciate that the electronic system 1102 may have a multitude of other configurations to achieve complex functionality in a compact form factor.
