论述了全数字控制系统中转子侧无环流交－交变频器的工作原理，讨论了正弦波输出的交－交变频器触发角的控制方案，设计了零电流检测电路. 该电路交-交变频器不允许有过大的死区，引入触发脉冲信号以识别真假“有电流”信号，提高了零电流检测电路的准确性.

The cyclo-converter of a digital control system in the rotor no-ringing current is described in this paper, the triggering angle modulation method of the sine-wave cyclo-converter is carried out. Zero-current dectection circuit is planned according to its problem: the cyclo-converter does not permit too much dead region so that sensitivity is improved. In order to distingnish “current”signal，we draw into trigger pulse signal.
