Abstract:

Basic battery charging configurations permitting control of charging power by use of switch modulation methods are presented. Circuits using both transistor and silicon controlled rectifier switch power modulators are described and compared. Pulse-width and pulse frequency modulation methods are examined from the standpoint of suitability for control of charging power. It is conculed that use of pulse-width switch modulation control of charger power results in a smaller required output circuit smoothing choke than is required using the pulse frequency control method.
