摘　　要：提出了一种利用串联有源电压质量调节器(Active Voltage Quality Regulator,简称AVQR)自身的IGBT开关和负载电流信号强迫旁路双向晶闸管(SCR)电子转换开关快速换流的控制方法,实现了对AVQR的快速投入和切除控制,其投入的响应时间小于900μs,大大提高了AVQR的工作性能。By means of the inherent IGBTs in the series active voltage quality regulator （AVQR） and the load current signal,a control method to force the conducting bypass thyristors into eommutating fastly is presented,then a fast switch-on and -off control algorithm is implemented for an AVQR, and its switch-on response time is below 900 μs, depending on the load and specific characteristics of the thyristors utilized, and the performance of the AVQR is greatly improved.
