Research on Direct Power Control Technology of PWM Rectifiers
Abstract:The paper based on the mathematical model of three-phase voltage source PWM rectifier, according to the advantage of direct power control (DPC) system, designed the model of voltage source PWM rectifier DPC control system which based on hysteresis control model. Simulation analysis shows that three-phase voltage source PWM rectifier DPC system which based on hysteresis control has stable DC output, high power factor, quick dynamic response and so on.
Keywords: PWM rectifier;hysteresis control direct power control instantaneous power
