12 V Car battery charger based 7812

Description of the 12V battery charger electronic scheme : Below is a very simple circuit that can be used to charge 12v car battery. In this circuit there is installations to control the charging current and voltage. The circuit is based on the circuit MC78T12ABT IC from Freescale. IC is actually a 7812 with a TO-3 package with a capacity of 3A. T1 is a transformer to reduce voltage and the diodes D1 and D2 perform as a rectifier. C1 capacitor is to filter and the capacitor C2 Continue reading
