Abstract Permanent magnet synchronous generator (PMSG) system consists of the PMSG itself and a power converter. Pulse width modulation (PWM) rectifier control methodology for the PMSG system with wide- speed-range operation and DC load is studied in this paper. By establishing the small signal analysis model of the PMSG and the transfer function of the PWM rectifier, the influence of control parameters on the system performance is analyzed, and the optimization method of the control parameters is achieved. The system model is verified by simulation and experimental results. It is shown that due to the application of the optimized control parameters, the PMSG system has a good voltage follow performance and anti-load-disturbance ability over a wide speed range of 200~2000r/min, and realizes high-performance voltage regulation.
