摘要

In the double closed loops control strategy of three-phase voltage source PWM rectifier in the synchronous reference frame, the linear PI control is usually adopted in the voltage control loop, which cannot reflect the nonlinear nature of the PWM rectifier, and restricts the system's control performance. According to the analyses on the voltage equation of the PWM rectifier, a voltage control strategy with which the capacitance's energy is taken as a variable is proposed, so the linearization control in the voltage loop is realized, and the dynamic response performance of the voltage is improved. Simulation results confirm the validity of the mentioned strategy.
