Abstract

The voltage and current double closed-loop control strategy is usually used in three-phase voltage-source PWM rectifier control. However the nonlinear characteristic of the voltage equation gives more trouble to design this control strategy. A comparative study of two kinds of linear instantaneous power control strategies for PWM rectifier is presented, who are that only using a linear PI regulator and that using a PI regulator with load power feed-forward. It is pointed out that the system response can greatly be faster by using the load power feed-forward contro1. On this basis, according to the nonlinear characteristic of voltage equation, the control strategy based on load power feed-forward control is modified, which not only inherits the advantages of the fast response of the control strategy, but also realizes the linear control of the output voltage. MATLAB simulation and experimental results indicate the validity of the control strategy.
