摘要
电网的电压是恒定的，要得到可调的交流电压必须使用调压器。常用的用晶闸管组成的调压器需要专用的触发装置和同步电源，结构复杂．本文介绍一种由双向可控硅组成的、不需要专用触发器和同步电源的三相自动调压器．
Network three - phase AC voltage is constant. To get AC voltage regulated, AC voltage regulator is required. Since the voltage regulator which consists of thyristor requires special trigger and synchro power supply,its construction is complex. In this paper,we have introduced new AC automatic Voltage regulator which consists of double direction thyristor and does not require special irigger and synchro power supply.
