Secondly, a current for it is developed, which consists of a bridge zeromodulation current, signal amplifier and analog filter.
然后为其设计了信号放大、滤波和调零电路；

Double space vector modulation can realize zero current commutation of the rectifier side, greatly reduce the switch loss, and improve the efficiency of the converter.
双空间矢量调制两级协调控制能实现整流级零电流换流，极大地减少了开关损耗，提高了变换器的效率。
