Abstract

The present invention provides an energy feedback power supply load circuit suitable for an AC-DC conversion unit and a method thereof. The energy feedback power supply load circuit includes a DC-DC conversion unit, a first full-wave rectification unit, and a second full-wave rectification unit. unit, filter unit, DC-AC conversion unit, power supply, the DC-AC conversion unit supplies AC power to the power supply, the power supply delivers electric energy to the DC-DC conversion unit, the DC-DC conversion unit The output DC power is delivered to the DC-AC conversion unit. The method includes the steps of: supplying alternating current to a power source; outputting the energy of the power source and converting it into a voltage; rectifying and filtering the voltage to output alternating current to the power source, thereby forming a power source output electric energy recycling. The power supply load circuit can recycle the output electric energy of the power supply, so as to save electric energy, reduce the input power distribution power, and promote environmental protection.

Description

technical field [0001] The invention relates to a power supply aging load circuit and a method thereof, in particular to an energy feedback power supply load circuit suitable for an AC-DC conversion unit and a method thereof. Background technique [0002] In order to ensure product quality, the power supply of the AC-DC conversion unit needs to undergo aging tests for several hours or even several days before leaving the factory. The existing aging load of the power supply is a resistance. When aging, the output power of the power supply is consumed by these resistive loads and converted into heat energy. The output power of the power supply is wasted in vain, and it also generates heat and dust pollution, which affects the environment. [0003] figure 1 It is a block diagram of a traditional power supply load in the prior art, which includes an AC mains input, a power supply 100 , and a resistance load 200 . The electrical energy output by the power supply 100 is consumed...
