The Multifunction charger introduced in the example can charge nickel-hydrogen batteries and alkaline cells with simple circuit and material.It can charge four pieces of battries at the most one time and stop charging automatically when batteries are fully charged.Circuit's Work PrincipleThis multifunction charger consists of mains transformer,T, rectifier bridge,UR, three-terminal adjustable IC regulator,IC,transistor,V1-V4,LED,VL1-VL4,resistor,R1-R9 and potentiometer,RP and it's showed as the picture 5-68.The alternating voltage(220v) changes to 6v volts d.c.when it passes T and UR.The voltage is added to VLl-VL4's anode as charging voltage and used as charging reference voltage when it passes IC.
