摘　　要：过零触发比例选控电路以可控硅作为触发开关功率元件，它把负载与电源接一定的通断率接通和断开，使负载上获得完整的正弦波形，并使其功率得到精细的调整．电路可广泛应用于数字化仪器及自动化控制设备中．Using SCR as trigger switch power elements, the over-Zero trigger proportion selector circuit can make load and power on-off according to certain break-make ratio and make load to acquain the integral sine wave. The load power also can be fine adjusted. The circuit can be generally used in digital instruments and automatic control equipment.
