Add DC to AC power module by using Ethernet power supply principle

This author is about adding a DC to AC power module by using the Ethernet power supply principle, especially a DC power receiving module that can output the power source device (PSE) DC through DC conversion AC and DC conversion. The DC modules are integrated to provide computer DC output devices and other AC output devices.

Power over Ethernet (POE) is a technology that can transmit power and data to a device through a twisted pair cable in an Ethernet network. Devices such as VoIP, wireless base stations, webcams, hubs, computers, etc. can be powered by POE technology. No additional power outlets are available for electronic devices that can be powered by Ethernet. It can be used, so at the same time, the time and money for configuring the power cord can be saved, and the cost of the entire device system is relatively reduced.

However, currently Ethernet Powered Technology (POE) has been widely used in different electronic products. However, there are still not many computer systems. Nowadays, the CPU of the motherboard and the North and South Bridge chips are being introduced, and the power demand is greatly reduced. It is no longer difficult to apply the Ethernet Power Supply Technology (POE) to the computer.

In fact, constructing a complete Ethernet-powered technology (POE), Power Source Equipment (PSE) idles the network route RJ-45, providing power to the network power supply module (PD), where PD The module then converts 57V to 19V for use by related equipment.

The reason is that the main purpose of this creation is to provide a DC-to-AC power module using the Ethernet power supply principle, and use the Ethernet power supply technology (POE) to output the DC voltage of the power source equipment (PSE). Some are directly connected to DC power supply equipment, such as computer unit DC power supply equipment; the other part is connected to AC power supply equipment, such as computer monitors or peripherals, via DC to AC transfer module.

In order to achieve the above objectives, the author adopts the following technical means: a DC-to-AC power module is added by using the Ethernet power supply principle, and the DC voltage output from the power supply device (PSE) of the Ethernet power source is connected. To the Ethernet power receiving module, connect the DC to DC module or the DC to the AC module via the Ethernet chip and the bridge rectifier inside the Ethernet power module, respectively for DC power supply equipment or AC power supply device output.
