摘要
采用空间电压矢量控制技术对三相电压型PWM整流器分析和建模,采用简化型的SVP-WM控制策略来实现PWM的控制,通过Matlab/Simulink对模型和控制方法进行仿真。仿真结果证明这种控制的动态响应速度快,直流侧电压稳定,交流侧电流为正弦波,且电压电流同相位,实现了单位功率因数,有效的抑制了谐波的产生。
Three-phase voltage PWM rectifier is analyzed and its model is built in this paper by adopting SVPWM control technology. A simple SVPWM control strategy is adopted to realize PWM control. Simulation of the model and control method is carried out by matlab/simulink. Simulation result proves that this control method have the advantages of fast dynamic response, stable voltage in DC side, sine current waveform in AC side and same phase position between current and voltage, so the unity power factor is realized and harmonic is eliminated effectively.
