The AC voltage regulator introudced in the example has the features of broad voltage regulation range(102-262V),perfect protection effects(powerdown delay electrification,380V phase dislocation-proofing and lightning protection and statics-proofing etc.) and high sensitivity and it's available in families with unsable line voltage.
Circuit's WorkPrincipleThe AC voltage regulatorcircuit is composed of +5V voltage regulation circuit,voltage test circuit,control circuit,protection circuit and voltage regualation output circuit and it is showed as the picture 5-49.The +5V voltage regulation circuit consists of fuse,FU1-FU3,autotransformer,T,commutation diode,VD1,filter capacitor,C1,three-terminal voltage regulation IC,IC1,resistor,R21 andpowersupply indication LED,VL.
