Simulation research on direct power control system of three phase boost type PWM rectifier

Min Zhao

Abstract

Based on the vector control principle of three-phase PWM rectifier,the power control model is used to construct,according to the power control model,the direct power control strategy based on three-phase voltage-type PWM rectifier control system of components and principles are analyzed in detail.In Matlab/Simulink environment,a direct power control system simulation model is built,with the traditional use of double closed loop control of voltage and current control strategies are compared.Simulation results show that,DPC system has good dynamic and static performance,simple structure,no PWM modulator module,the advantages of high power factor and so on.
