Decoupling Control of Three Phase Boost Type PWM Rectifiers Based on Storage Function

Article Preview

Abstract:

Based on the model of three phase boost type PWM rectifier in synchronous dq coordinates, a simple control law, which transforms the rectifier control system into decoupling and linear one,is deduced based on storage function. New rectifier control system based on the law has many advantages, such as simpler structure, and low total harmonic distortion,and good robustness for load. Decouping control system of three phase boost type PWM rectifiers is proved feasible by simulink simulation.
