Battery Charger Circuit Using Scr. So if you want to charge your battery with ac. A simple battery charger based on scr is shown here here the scr rectifies the ac mains voltage to charge the battery when the battery connected to the charger gets discharged the battery voltage gets dropped this inhibits the forward biasing voltage from reaching the base of the transistor q1 through r4 and d2 this switches off the transistor when the transistor is turned off the gate of scr h1 gets the triggering voltage via r1 d3 this makes the scr to conduct and it starts to rectify.
When the battery almost reaches its full terminal voltage full charge high current charging is cut off and slow charging trickle charging is still done. At full charge condition the charging is totally cut out by the control of the microcontroller. 12v battery charger circuit using scr.
Also it uses the 6v battery.

This battery charger circuit differs from the norm in a number of ways all of which make it difficult to understand. The zener diode and scr are main parts. This is a simple circuit that can charge a battery by using an scr and a lm311.
