BACKGROUND
1. Field
The disclosure relates to a dielectric heating device.
2 Description of Related Art
Dielectric heating is a technique of heating an object using a short-range electric field. When high-frequency power of several tens of MHz is applied to an object (e.g., an object to be heated), a high-frequency electric field is generated so that polar molecules in the object are rotated or vibrated, heating the object.
The dielectric heating technology is technically similar to that of the conventional microwave oven, but the dielectric heating device is driven at a frequency lower than the frequency used in the microwave oven, so that the penetration of heat is deepened and uniform heating is possible. It may be applied to food care (e.g., defrost, aging, drying, sterilization), clothing care (e.g., drying), skin care, brand-new drying methods, or carbon capture using the nature of uniform heating.
The above information is presented as background information only to assist with an understanding of the disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the disclosure.

FIG. 1 is a view for describing a power amplifier according to an embodiment of the disclosure.
The power amplifier 1 may include a transistor 2, a radio frequency (RF) choke inductor Lchk 3, a shunt capacitor Csh 4, and a serial LC resonance circuit 5. The shunt capacitor 4 and the serial LC resonance circuit 5 may constitute a load network of the power amplifier 1.
The transistor 2 may operate by receiving a driving voltage VDD from an input power source, and may be turned on or off by receiving an input signal 6 (or a control signal) in a pulse form (e.g., a square wave) through an input terminal (e.g., a gate). For example, the transistor 2 may include a bipolar junction transistor (BJT) or a metal oxide semiconductor field effect transistor (MOSFET). Referring to FIG. 1, when the transistor 2 is an N-channel MOSFET (N-MOS), the input signal 6 may be a gate voltage applied to the gate terminal of the N-channel MOSFET. The source of the transistor 2 may be connected to a ground, and the drain thereof may be connected to an output node 7.
The RF choke inductor 3 may block the transfer of the RF signal from the input power source to the transistor 2 so that only the direct current (DC) current is transferred to the transistor 2.
The shunt capacitor 4 may be connected in parallel with the transistor 2 and may be discharged or charged while the transistor 2 is turned on or off. The shunt capacitor 4 may be a separate capacitor connected in parallel with the transistor 2, and may be described as including an internal capacitance (e.g., drain-source capacitance Cds) of the transistor 2.
RF power may be generated based on the transistor 2 being turned on or off according to the input signal 6, and the generated RF power may be transferred to the serial LC resonance circuit 5 through the output node 7. More specifically, when the transistor 2 is turned on (e.g., when the transistor 2 is saturated), the transistor 2 may be electrically shorted and thus be interpreted as a short circuit for the ground connected to the source, and the voltage of the output node 7 may be interpreted as zero. The current flowing to the transistor 2 through the RF choke inductor 3 may gradually increase. Thereafter, when the transistor 2 is turned off, the current flowing through the RF choke inductor 3 is directed to the shunt capacitor 4, and as the shunt capacitor 4 is gradually charged, the voltage of the output node 7 (e.g., the voltage across two opposite ends of the shunt capacitor 4) may increase until the maximum value is reached. Thereafter, as the shunt capacitor 4 is gradually discharged, a current flows from the shunt capacitor 4 to the serial LC resonance circuit 5 through the output node 7, and the voltage of the output node 7 (e.g., the voltage across two opposite ends of the shunt capacitor 4) may gradually decrease. In the power amplifier 1, for a high-efficiency operation (e.g., to minimize the power consumed by the transistor 2), the transistor 2, the shunt capacitor 4, and the input signal 6 may be configured so that, after the transistor 2 is turned off and before the transistor 2 is turned on again (e.g., before the current starts to flow again to the transistor 2 through the RF choke inductor 3), the voltage of the output node 7 (e.g., the voltage across two opposite ends of the shunt capacitor 4 and the drain-source voltage of the transistor 2) gradually decreases to 0 and the amount of change in which the voltage of the output node 7 decreases becomes 0. Thereafter, when the transistor 2 is turned on again, the current flowing through the RF choke inductor 3 may be directed to the transistor 2, and the voltage of the output node 7 may be maintained at zero while the transistor 2 is in the on state. As described above, as the drain-source voltage (e.g., the voltage of the output node 7) of the transistor 2 is 0 while the transistor 2 is in the on state and the current flowing through the RF choke inductor 3 is directed to the shunt capacitor 4 while the transistor 2 is in the off state, the current flowing to the transistor 2 through the RF choke inductor 3 is 0 (in other words, a period in which the drain-source voltage of the transistor 2 is non-zero and a period in which the drain-source current is non-zero do not overlap), and thus, the power consumed in the transistor 2 is ideally 0, enabling a high-efficiency operation of the transistor 2. However, in a non-ideal case, since the power amplifier 1 generates a signal (or RF power) based on the transistor 2 being turned on or off, the generated signal (or RF power) may include not only a desired frequency component (e.g., a fundamental component of the operating (resonant) frequency) but also a harmonic component of the second order or more, and power consumption may occur in the transistor 2 due to the harmonic component of the second order or more.
As described above, a current may flow from the RF choke inductor 3 to the transistor 2 or the shunt capacitor 4, or a current may flow from the shunt capacitor 4 to the serial LC resonance circuit 5 based on the transistor 2 being turned on or off according to the input signal 6 in the power amplifier 1, thereby generating an alternating current (AC) current. The generated AC current may be output to the outside (e.g., the matching network 8 and/or the load 9) through the serial LC resonance circuit 5, thereby generating an AC voltage in the load 9. The above-described generation of the AC current based on the above-described transistor 2 being turned on or off may be described as generation of a signal (or RF power) based on the transistor 2 being turned on or off.
The serial LC resonance circuit 5 may include an inductor Lr and a capacitor Cr connected in series with each other, and unlike illustrated, the serial LC resonance circuit 5 may include two or more inductors and two or more capacitors. The serial LC resonance circuit 5 may be configured to have a resonant frequency corresponding to (e.g., identical to) the operating frequency so as to resonate with the operating frequency of the input signal 6. For example, the serial LC resonance circuit 5 may be designed to include an inductor Lr and a capacitor Cr having an inductance value and a capacitance value so that the reactance value of the equivalent impedance of the serial LC resonance circuit 5 becomes 0 at the operating frequency of the input signal 6.
The matching network 8 may be connected to an output terminal of the power amplifier 1 (e.g., connected in series to the serial LC resonance circuit 5), and may provide impedance matching for matching the output impedance of the power amplifier 1 to the load 9.
The load 9 may include at least one hardware component (e.g., a circuit element) that receives, or operates by receiving, a signal (or RF power) generated by the power amplifier 1.

A dielectric heating device (e.g., the dielectric heating device 300 of FIG. 3) may include a high-frequency power source 210 and a plurality of electrodes (e.g., the first electrode 221 and the second electrode 222). A high-frequency electric field 230 may be provided between the first electrode 221 and the second electrode 222 by the high-frequency power source 210.

The dielectric heating device (e.g., the dielectric heating device 300 of FIG. 3) may provide a high-frequency electric field 230 between the first electrode 221 and the second electrode 222, thereby heating the object disposed between the first electrode 221 and the second electrode 222. The object may be heated by the motion of the polar molecules 240 in the object. The polar molecules 240 in the object may be positioned on the surface and inside of the object, and the portion where the object is heated may be determined according to the position where the polar molecules 240 are disposed in the object. The object may be uniformly heated due to the motion of the polar molecules 240 in the object.
The dielectric heating device (e.g., the dielectric heating device 300 of FIG. 3) may control freezing of the object disposed between the first electrode 221 and the second electrode 222 by providing the high-frequency electric field 230 between the first electrode 221 and the second electrode 222. For example, the dielectric heating device (e.g., the dielectric heating device 300 of FIG. 3) may provide a high-frequency electric field 230 between the first electrode 221 and the second electrode 222, thereby controlling supercooling of the object disposed between the first electrode 221 and the second electrode 222 or performing an operation of storing the object at a pre-freezing point.
An electronic device (e.g., the electronic device 300 of FIG. 3) may heat the object disposed between the first electrode 221 and the second electrode 222 by providing the high-frequency electric field 230 between the first electrode 221 and the second electrode 222. The object may be heated by the motion of the polar molecules 240 in the object. The polar molecules 240 in the object may be positioned on the surface and inside of the object, and the portion where the object is heated may be determined according to the position where the polar molecules 240 are disposed in the object. The object may be uniformly heated due to the motion of the polar molecules 240 in the object.
Hereinafter, the operation of heating the object will be mainly described, but it will be understood by one of ordinary skill in the art that the dielectric heating device (e.g., the dielectric heating device 300 of FIG. 3) may perform operations other than the operation of heating the object, the operation of supercooling the object, and the operation of storing the object at a pre-freezing point by providing the high-frequency electric field 230 between a plurality of electrodes (e.g., the first electrode 221 and the second electrode 222) of the dielectric heating device (e.g., the dielectric heating device 300 of FIG. 3).

The power supply unit including the power source 310 and the driving circuit 330 of FIG. 3 may be represented as a power source V and a characteristic impedance R in the first circuit diagram 410 of FIG. 4. In order to describe a case in which the dielectric heating device 300 includes one or more power sources 310 and one or more driving circuits 330, the power supply unit including the one or more power sources 310 and the one or more driving circuits 330 may be represented as one or more power sources V1, Vn−1, and Vn in the circuit diagram 1910 of FIG. 19 to be described below.

FIG. 5 may be described with reference to FIGS. 3, 4, and 6. FIG. 6 is a view for describing a load circuit of a dielectric heating device according to an embodiment of the disclosure.
Referring to FIG. 5, according to an embodiment, the dielectric heating device 300 (e.g., the load circuit 320 of the dielectric heating device 300) may include a plurality of electrodes (e.g., the first upper end electrode 511, the second upper end electrode 512, and the lower end electrode 520). The plurality of upper end electrodes (e.g., the first upper end electrode 511 and the second upper end electrode 512) included in the load circuit 320 may be positioned on substantially the same plane. The lower end electrode 520 included in the load circuit 320 may be disposed on a plane parallel to the plane formed by the plurality of upper end electrodes (e.g., the first upper end electrode 511 and the second upper end electrode 512).
According to an embodiment, the first upper end electrode 511 and the lower end electrode 520 may form a first capacitor C1. A first area (e.g., an area corresponding to the first upper end electrode 511) of the first upper end electrode 511 and the lower end electrode 520 may form a first capacitor C1. The second upper end electrode 512 and the lower end electrode 520 may form a second capacitor C2. A second area (e.g., an area corresponding to the second upper end electrode 512) of the second upper end eyelash 512 and the lower end electrode 520 may form the second capacitor C2. Referring to FIGS. 5 and 6, the first capacitor C1 and the second capacitor C2 included in the load circuit 320 may share the lower end electrode 520.

For example, the area of the first upper end electrode 511 and the area of the second upper end electrode 512 may be substantially the same. For example, the size of the first area of the lower end electrode 520 corresponding to the first upper end electrode 511 and the size of the second area of the lower end electrode 520 corresponding to the second upper end electrode 512 may be substantially the same.
