ABSTRACT:
A DC voltage up-converter circuit having an inductor in series between the relatively low value of DC voltage and the stepped up output of the circuit, wherein the output end of the inductor is periodically switched to ground potential and an output storage capacitor stores the energy surges which result when the ground connection is disconnected. The cathode of a zener diode is connected to the output to provide a limit to the output of the circuit and the anode of the zener diode is connected to means for control limiting the amount of current through the switching means when said ground potential is connected.
