RESEARCH ON CONTROL STRATEGY OF THREE PHASE CURRENT SOURCE PWM RECTIFIER BASED ON P+R CONTROLLER AND AUTO DISTURBANCE REJECTION CONTROLLER ADRC

摘要

In order to solve the problem of high power factor when a low content of harmonic current and the performance index of DC side, the key problem of PWM control strategy was proposed. The theoretical analysis and experimental results proved the feasibility and effectiveness of the PWM controller based on ADRC controller and the experimental results proved the feasibility and effectiveness of the scheme.
