A SVPWM Compensation Current Tracking Control Method Based on dq Transformation for Shunt Active Power Filter

Abstract

The working principle of the shunt active power filter, the main circuit structure and the instruction current operation circuit including the DC side voltage control link are introduced. A SVPWM compensation current tracking control method based on dq transformation is proposed, and the simulation model is built by using the PSIM9.0. It is proved by PSIM simulation that the method has simple control and can accurately track the change of reference current, effectively reduce the switching frequency of PWM converter, and verify the superiority of the method.
