Novel modulation strategy of Direct Power control for PWM rectifier

In view of the present traditional switch table insufficiency, analyzed the working principle and the characteristic of direct power control (DPC) for PWM rectifier, this paper propose that constructing switch table to improve adjustment ability and performance of rectifier with the new switch table and space vector modulation method. The simulation results show that with the novel strategy out of control phenomenon could be weaken obviously, active power and reactive power could be controlled effectively. That ensure the rectifier operates under unit power factor and realizes the electric power electronic installation green environmental protection research.
