ABSTRACT:
An energy saving DC-DC converter circuit is disclosed having two energy efficient means which operate in tandem, an energy conserving means (30, 8, 1) and a voltage doubling means (26). These energy efficient means are applied in combination with elements commonly found in DC-DC converter circuits, namely an AC voltage generator (2), a transformer (3) for stepping up the generated AC voltage, and means (31) for storing the converted DC voltage. The energy conserving means is connected to the DC voltage storage means (31). It comprises a resettable inhibit circuit (1) which cuts off the provision of DC voltage for conversion for a predetermined interval when the output of the converter exceeds a predetermined level. The voltage doubling means is reponsive to outputs of the inhibit circuit (1) of the energy conserving means and the AC voltage generator (2). It provides a phase inverted waveform of the generated AC voltage on one of two leads to the AC voltage step-up transformer (3).
