The AC voltage regulator introudced in the example can control and regulate voltage automatically,cut off when it is idle load and voltage is over to save engery and protect the regulator.The regulator's input voltage range is from 65V to 250V,output voltage range is 195V to 230V and output power is 500W.
Circuit's Work Principle
The AC voltage regulator circuit is composed of power supply voltage control,voltage test,control circuit and time delay circuit and it is showed as the picture 5-41.The power supply voltage control consists of mains transformer,T,rectifier bridge,UR,filter capacitor,C6 and C7,three-terminal voltage control IC,IC2 and power indication LED,VL3 and current-limiting resistor,R14.
