A Control Scheme of Three-Phase CSR Based on SVPWM
The conventional space vector pulse width modulation (SVPWM) control scheme of three-phase current-source PWM rectifier (CSR) is analyzed in this paper, and proposes a new SVPWM control scheme based on the improved algorithm. This algorithm is simple and can be digital realized easily. A system model of three-phase SCR based on this control scheme is designed. Static, dynamic results of simulation and experiments are also presented, which demonstrate the correctness and validity of the improved SVPWM control scheme.
