ABSTRACT:
A permanent magnet alternator is connected directly across the battery through a full-wave bridge rectifier. The bridge includes a pair of controlled rectifiers which are selectively rendered conductive to charge the battery through the bridge when the battery voltage drops below a preset value. A Zener diode and one transistor monitor the battery voltage and control a second transistor which in turn controls gating current from the alternator to the controlled rectifiers.
