Decoupled control and DSP implement of PWM rectifier

On the basis of deducing and analyzing the mathematical model of PWM rectifier, a new method was put forward, which realized current decoupled control in d - q synchronous frame. The cascade control structure and the high performance space-vector pulse-width modulation (SVPWM) technique were adopted. A full digital PWM rectifier was implemented by using digital signal processor (DSP). With the full utilization of the inner resource and high-speed data processing ability of DSP, the rectifier fulfilled complex control algorithms and operation in real-time. Experiment result indicates that this control method has a good performance and is an ideal way for the implementation of PWM rectifier.
