Abstract

An new idea of indirect current control system of three-phase PWM rectifier based on DSP is presented in this paper, and a new phase- amplitude control method is proposed. The lag angle is regarded as the input variable. The control algorithm and the digit algorithm of the space vector control are implemented with TMS320F240 chip. The experimentsshowsthat the system fulfills the unity power factor and regulates the output DC voltage according the voltage reference.
