ABSTRACT:
A battery charger to recharge a battery comprises a transistor switch coupled with a cable loss compensator. Additionally, the battery charger includes a comparator, a current limiter, and a differential amplifier. The circuits are created from discrete components, and particularly include individual transistors. A smoothing network takes the signal from the switch and passes it along to the battery for recharging.
