ABSTRACT:
A floating battery feed circuit comprising a switching-mode, flyback power converter wherein a capacitor connected to a converter transformer winding develops a relatively low voltage used to energize the converter control circuitry. The converter control circuitry prevents the operation of the battery feed circuit unless the voltage developed by the capacitor is above a predetermined magnitude. The power converter advantageously operates in only a constant-power mode regardless of loop impedance.
