The numerical control D. C. power-supply circuits-fixed introduced in the example uses metal touch button ,digital IC and electron switch IC to converse the magnitude of output voltage.Compared to D. C. regualted power-supply cf traditional mechnical range switch,it has the advantage of lowbreakdown and convenient operation. Work's Principle of the Circuit The numerical control D. C. power-supply circuits-fixed is composed of mains circuit,free-running multivibrator,counting distributor,analog switching circuit and control circuit and it is showed as the picture 5-34.The mains circuit consists of mains transformer,T,rectifier bridge,UR,capacitor,C1-C5,resistor,R9,R10,diode,VD1,VD2,three-terminal integrated regulator,IC1 and zener diode,VS.
