Abstract
A dual voltage motor vehicle electrical system. First and second batteries are series connected across the output terminals of a battery charging generator. A converter is provided that can charge the first battery from the second battery or charge the second battery from the first battery. The voltages across the batteries are sensed and the battery with the lower voltage is charged from the other battery. The system has current limit and temperature limit controls for protecting semiconductor switches that are utilized in the system.
