Abstract

This paper presents a new idea of indirect current control system of three-phase PWM rectifier based on DSP. A new phase-amplitude control method is proposed. The lag angle ξ is regarded as the input variable. The control algorithm and the digital algorithm of the space vector control are implemented with TMS320F240 chip. Experiments show that the system realizes the unity power factor and regulates output DC voltage according to the voltage reference.
