The Simulation of a Control Method for Three-phase Voltage-type PWM Rectifier

MA Chun-hong

Abstract

Based on the circuit of three-phase voltage-type PWM rectifier,the mathematical model of three-phase voltage-type PWM rectifier is established.A voltage cycle control method is presented.The simulated results show that the control method is feasible,has a simple controllable structure and less measuring variables,doesn't need current sensors,has a low cost,being easy to be implemented and has the practical value for engineering applications.
