ABSTRACT This project presents the design and construction of a battery charger. A battery charger is an electrical/electronic device used to put energy into a secondary cell or rechargeable battery by forcing an electric current through it.  The system  consists of a step down transformer, an AC to DC converter and a DC voltage regulator. The... Continue Reading

ABSTRACT The practical importance of a battery charging unit in today’s world cannot be over emphasized. This is so since these batteries or accumulators are immensely needed by automobiles and in science laboratories. This thesis describes the methodical approach to the design and construction of any battery changer. However the procedure... Continue Reading
