一种无电流过零畸变的Vienna整流器改进调制策略及控制方法

Vienna rectifier with simple structure, which has gained popularity in recent years for ac to dc power conversion for many industrial applications such as electric vehicle charging systems and uninterrupted power system (UPS) systems, accomplishes the operation of unit power factor. However, the distortion of the input current near the zero-crossing point is a puzzle that will increase the current...
