ABSTRACT:
A resonant current-driven power source is disclosed. Preferably, the power source is a DC to DC converter regulator including a inductor and capacitor electrically coupled to one another and an input inverter which converts an input DC voltage into an AC voltage having substantially no DC component and applies the AC voltage across an LC circuit in a manner which causes the inductor and capacitor of the latter to resonate with one another whereby an AC voltage appears across the capacitor. An output circuit converts the AC voltage appearing across the capacitor into a DC output voltage. A control circuit is provided for controlling the operation of the inverter circuit in a manner which controls the magnitude of the output voltage. The inverter circuit also includes a step-up transformer for increasing the magnitude of the AC voltage across the LC circuit to a value many times greater than the input DC voltage.
