Compensation equipment for fluctuations in A.C. source voltage
摘要：
An AC voltage regulator which detects the instantaneous supply voltage in a phase shifter and compares it with the reference voltage by a comparator circuit so that in response to the output signals from the comparator, the firing angle of the thyristors connected to a supply voltage circuit may be controlled in order to maintain constant the effective load current.
摘要（中）：

一种AC电压调节器，其检测移相器中的瞬时电源电压，并通过比较器电路与参考电压进行比较，使得响应于来自比较器的输出信号，连接到电源电压电路的晶闸管的触发角可以 以控制有效负载电流的恒定。
