摘要
Abstract
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.关键词
