【Abstract】 As the raulti - power output generator system requires putting out high quality DC voltage, the application of SVPWM control strategy based on voltage orientation in the system is presented in this paper. It tends to improve the dynamic and static quality of rectifier by using the new, easily realized digital vector combination method. Build up mathematic model of three - phase PWM rectifier, and give out the simulated and experimental wave of the rectifier under the condition of the input voltage and load change. The results fully show the validity and practicability of the scheme.更多还原
