数控交流稳压电源中零电流触发的研究

Study on Yero-Current Trigger in Numeric Control Alternating Current Stabliging-Valtagemais

本文介绍了数控交流稳压电源中零电流触发脉冲的前沿相位和脉冲宽度。流过双向晶闸管的电流与零电流脉冲宽度的关系，电压控制信号的最佳到达相位。

With regard to gero-current trigger in numeric control alternating current stabiliging-Valt-age mains,this paper introduces its qorwacd phose position, the width of the pulse,the relation-ship between the cussent passing through the bidirectional crystal gastriode and the wilth of gero-current pulse and the best phase position for the valtage control signals.
