Simulation Design of Single-phase AC Electronic Load

Abstract

With the development of power electronics technology, a variety of power supplies are used in people's production and life. The characteristics of the power supply will greatly affect production and life. Therefore, it is necessary to conduct strict tests on the power supply. The traditional load has the disadvantage of consuming a lot of energy, and the AC electronic load solves the disadvantages brought by the traditional load.This paper takes single-phase AC electronic load as the research object. Based on the overall scheme design and topology research of the power electronic load system, the energy-consuming power electronic load is simulated first, the simulation model is constructed, and the main circuit is designed. Parameter, realize the load simulation function; further carry out the simulation research on the single-phase energy-fed power electronic load, the current generation unit design adopts PI+ repetitive control strategy, and the energy feedback unit adopts double closed-loop control strategy. After testing, the simulation current generation and energy are realized. The feedback function completes the overall simulation design of the single-phase AC electronic load.
