Research of Hysteresis PWM Rectifier Based on the Current Vector Control

According to high power factor and the actual project needs which are requirements of three-phase rectifier control as known, the research of three-phase PWM rectifier is based on the current vector control. The system still adopts hysteresis current control strategy. This system not only truly reflect the operational status of PWM rectifier, but also make the design of control system easier, and has much lower dependence on the PI parameters of the outer voltage regulator than conventional hysteresis PWM rectifiers. The system works well even under unbalance power conditions. Simulation and experimental data both confirm the simple and effective methods of control and low dependent of PI parameters.
