(a) Field of the Invention
The present invention relates to using power over ethernet to augment a DC/AC (direct current/alternating current) power module inverter and application thereof, and more particularly to a POE (Power Over Ethernet) respectively providing the DC output from a PSE (Power Source Equipment) to a computer unit DC power equipment and other AC power equipment via integration of a DC/AC and a DC/DC module inverter.
(b) Description of the Prior Art
It is known that POE (Power Over Ethernet) is a technology for transmitting power and data to a device through a twisted pair wire in the Ethernet. Devices including internet telephones, wireless access points, web cameras, hubs, computers, and the like, can be supplied with power by the POE technology. As the electronic equipment powered by the Ethernet can be used without requiring an additional power socket, the time and money spent in configuring the power cable can be saved, thereby reducing the cost of the entire device.
Nevertheless, existing electronic equipment powered by POE technology are seldom used in computer systems. However, the continuous advancement of current CPUs on motherboards and North/South bridge chips have significantly reduced the amount of electricity required, thus, the problems of using POE applications in computers have been greatly reduced.
In effect, building a completely compliant POE involves a PSE (Power Source Equipment) providing power that is transmitted to a network PD (Powered Device) module using a RJ-45 (registered jack-45) network cable circuit. Wherein the PD module converts 57 volts to 19 volts for use by connected equipment.
Accordingly, the primary object of the present invention is to use a POE (Power Over Ethernet) to directly couple one proportion of the DC voltage output from a PSE (Power Source Equipment) to a DC power equipment, such as a computer unit DC power equipment, and couple another proportion of the DC voltage output to an AC power equipment, such as a computer monitor or other peripheral equipment via a DC to AC module inverter.
To enable a further understanding of said objectives and the technological methods of the invention herein, a brief description of the drawings is provided below followed by a detailed description of the preferred embodiments.
Referring to
The power output amount can be dynamically adjusted according to the known power input, and, in effect, is according to the computer system or monitor connected to the output power source.
Referring to
In conclusion, according to the above description of the embodiments, the present invention provides a POE, and a PD module couples the DC voltage from the PSE to a computer unit DC power equipment with DC voltage. In addition, the PD module can couple the DC voltage from the PSE to an AC power equipment via a DC to AC module inverter.
It is of course to be understood that the embodiments described herein are merely illustrative of the principles of the invention and that a wide variety of modifications thereto may be effected by persons skilled in the art without departing from the spirit and scope of the invention as set forth in the following claims.
