Abstract
Abstract A charging system for charging plural batteries from a generating coil without requiring a separate isolator to protect the circuit in the event of battery failure. The circuit includes a rectifying diode circuit including a plurality of parallel diode paths between the ends of generating coil and the terminals of the battery. There are a number of diode circuits at least equal to the number of batteries.
