摘　　要：引言：针对一般电气商店只能购买到小功率的调光器,设计一个千瓦级的大功率调光器,利用双向触发二极管与双向可控硅等元件构成调光电路,通过调节两个电位器,可以改变双向可控硅的导通角,从而改变通过灯泡的电流（平均值）实现从熄灭到最亮的连续调光,如果将灯泡换电熨斗、电热褥还可实现连续调温,体现了这种调光器的多用型。A kilowatt class high-power dimmer is designed for the general electric store,a kilowatt level high-power dimmer is designed.A dimming circuit is made up of two way trigger diode and bidirectional thyristor.By adjusting the two potentiometers,the conduction angle of the bidirectional thyristor can be changed,thus changing the current（average）of the bulb through the bulb.To realize the continuous light adjustment from extinguishing to the brightest.If the light bulb is changed to the electric iron and the electric heating mattress,the continuous temperature adjustment can be realized,which embodies the multipurpose type of the dimmer.
