A switched mode regulated DC to DC converter for supplying a regulated voltage to a load includes a switching frequency generator of a switching cycle having positive and negative portions. A device, responsive to the outputs of the switching frequency generator, accumulates a voltage during the positive and negative portions of the switching cycle. The demand for voltage by a load is sensed and circuitry generates a first and second trigger otuput during the respective positive and negative portion of the switching cycle when the accumulated voltage equals the sensed load voltage demand, the time required to generate the second trigger output being equal to the time required to generate the first trigger output. A transformer apparatus, responsive to the first and second generated trigger outputs, generates currents of positive and negative polarity during the positive and negative portions of the switching cycle. A first electronic switch, responsive to the generated currents of positive polarity, connects a load voltage source to a load during the positive portion of the switching cycle. Similarly, a second electronic switch, responsive to the generated currents of positive polarity, connects the load voltage source to the load during the negative portion of the switching cycle.
