Study on PSIM Simulation of Parallel Active Power Filter

Abstract

In order to suppress the harmonics in the power electronics, a method of SVPWM compensation current tracking based on dq transformation is proposed, which is simple to control and can accurately track the change of reference current, and this paper analyzes the working principle of parallel active power filter, main circuit structure, The command current operation circuit of DC side voltage control is included, and the simulation model is constructed by using PSIM 9.0. Through PSIM simulation verification, the method can effectively reduce the switching frequency of PWM converter and verify the advantages of this method.
