摘要
研究四开关三相逆变器电路,对PWM脉冲信号生成方式进行了分析。采用四个基本矢量控制的空间矢量控制方案,通过选取三个或四个基本矢量合成等组合方式来实现所需的电压输出,并对不同矢量合成组合进行研究。
Methods of generating pulse width modulation signals to control four-switch three-phrase inverters were put forward.And the four-basic-vector control in space vector control scheme was applied.The required output voltage was realized by synthesizing three or four basic vectors.Different vector combinations were discussed.
