摘　　要：传统的同步电机电源通常采用三相交流电通过三相不控整流模块转换成直流电,然后再经过变频器进行转换成驱动电机的交流电。这种模式下通常需要直流侧的大电容进行滤波,同时电网的电流是不可控的。针对这类缺点,提出使用一种交-直-交变换器进行驱动电机,双可控的转换器能够实现电网侧的单位功率因数,同时无需大电容进行滤波,节约成本并且提高了功率密度。The traditional synchronous motor power supply usually uses three-phase alternating current,which is converted into direct current by three-phase uncontrolled rectifier module,and then converted into AC drive motor through frequency converter.In this mode,a large capacitor on the DC side is usually needed for filtering,and the current of the grid is uncontrollable.In view of this kind of shortcoming,a kind of AC-DC-AC converter to drive the motor is proposed to use.The dual controllable converter can realize the unit power factor of the power grid side.At the same time,it does not need large capacitance to filter,which saves cost and improves power density.
