Abstract :
A new simplified control circuit for high performance three phase boost type PWM rectifier is presented. Based on the conception of vector control the AC vector processor (AD2S100) which serves for the AC motor vector control, is applied to high frequency rectification. Consequently, the control circuits are very much simplified. The transfer function of the system is deduced. The paper also presents a way to treat the nonlinear feature of the system. Simulation and experiment verified the proposed scheme
