Charger for NiCd Batteries

Charger for NiCd Batteries
This device is used to simultaneously charge for Ni-Cd batteries. The output step-down transformer AC 12V is fed to the rectifying diode bridge, assembled on a 4-diode 1N4007. Smooth capacitor C3 constant voltage supplied to the chip 7808 , the output of which will be regulated voltage 8 V. The transistor T1 ( BC547 ), incorporated on the emitter follower circuit is used as a voltage regulator, which determines the charge current. (more…)
