Abstract In this paper, the vector regulating principle of the phase and amplitude control for three-phase PWM grid-connected inverters is represented. To solve the problem of heavy impact current and slow dynamic current response when the system starts up, the start voltage prediction control and the current feed-forward control are proposed, and the ideal parameter of starting time and the value of feed forward adjustment are calculated by using the rate of the change of DC link voltage. The two methods improve the dynamic performance of the system in the phase and amplitude control. The experimental results carried out on a three-phase PWM grid-connected inverter prove the validity of proposed methods.
