摘要
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 。
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.
