摘要
针对多电源输出发电机系统要求输出高质量直流电压的问题,将基于电压定向的SVPWM控制策略应用于该系统的整流装置中,采用便于数字实现的矢量合成方法来提高整流器的动、静态性能,建立了三相PWM整流器的数学模型,并给出了整流器在输入电压和负载变动情况下的仿真和实验波形。结果充分表明了该方案的有效性和实用性。
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.
