English Description：
1. PWM rectifier is controlled based on IP / IQ method to realize active and reactive power decoupling control and DC capacitor voltage stabilization control. The voltage and current double closed-loop control structure based on the feedforward decoupling control is adopted in the system, in which the external voltage protection ensures the stable DC output, and the internal current loop improves the dynamic response speed of the current, and this kind of control structure is stable The control method makes the phase of the current consistent with that of the input voltage.
