Abstract

The invention provides an energy feedback power load circuit applicable to an alternating current-direct current shifting conversion unit and a method thereof. The energy feedback power load circuit comprises a direct current- direct current shifting conversion unit, a first full-wave rectification unit, a second full-wave rectification unit, a wave filtering unit, a direct current- alternating current shifting conversion unit and a power, wherein, alternating current is supplied to the power by the direct current-alternating current shifting conversion unit, electrical energy is transmitted to direct current-direct current shifting conversion unit by the power and direct current is output and transmitted to the direct current-alternating current shifting conversion unit by the direct current-direct current shifting conversion unit. The method comprises the following steps: alternation current is supplied to the power, the energy of the power is output and converted into voltage, and the voltage is commutated and wave filtered to output alternating current to the power, thus cyclic utilization of output electrical output by the power is formed. The power load circuit can recycle the output electrical energy of the power, which achieves the purposes of saving electrical energy, lowering power of inputting power distribution and promoting environmental protection.

Description

Technical field [0001] The invention relates to a power aging load circuit and a method thereof, in particular to an energy feedback power load circuit and a method suitable for an AC-DC conversion unit. Background technique [0002] In order to ensure product quality, the AC-DC conversion unit power supply needs to undergo aging tests for several hours or even days before leaving the factory. The existing power supply aging load is a resistance. When aging, the output electrical energy of the power supply is consumed by these resistance loads and converted into heat energy. The output electrical energy of the power supply is wasted in vain, and heat and dust pollution are also generated, 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 resistive load 200. The electrical energy output by the power supply 100 is not recycled by the electrical ene...
