三相定子 meaning in Chinese

threephase stator

Because the output voltage of pwm inverter is dissymmetry instantly , the common mode voltage appears as a result
由于pwm变频器的三相输出电压在瞬间并不对称，所以导致电机三相定子绕组的电压矢量和不为零，从而出现共模电压。
A novel resonant pole zvt three - phase pwm inverter circuit for three - phase ac motor driving is presented . the proposed circuit has the feature of being more flexible with three inverter arms in zvt process . using only one resonant inductance , the inverter can not only reduce the power loss of inductance but also avoid possibility of unbalance in motor ' s three stator windings
提出了一种针对三相交流电机驱动的新型谐振极零电压过渡三相pwm逆变器电路，该电路中三个逆变桥臂的零电压过渡更具有灵活性，仅使用一个谐振电感，既减少了电感损耗又防止了电机三相定子绕组可能存在的不平衡问题，并且谐振电感中残余能量能够回馈给电源；新型逆变器的辅助开关均工作在零电流开关条件下，并且控制逻辑简单。
