Constant Voltage Battery Charger

                        In order to use a battery until full life expectancy of it, should be ensured that conditions like deep discharging and over charging does not happen. The circuit ensures the full safety of the battery by providing a constant voltage charging mechanism. Thus over charging can be prevented.

Circuit Description.

                               In the circuit at first the AC supply is step down to 12V using a step down transformer rated 220V  primary 0-12V secondary, 1.5A Transformer. This is rectified using a bridge rectifier configuration and is later filtered using the 4700uF capacitor. Then this is applied to a series voltage regulator comprising of BC547 and MJE3055. The series pass element is MJE3055. VR 1 is used to adjest the output voltage.
