Abstract

A DC-to-DC converter, comprising: inverter means for receiving a DC input and providing as an output a high-frequency, alternately pulsed current waveform; a control winding for receiving the output of the inverter means, the control winding being wound on a common bobbin with first and second tank windings, the windings de-coupled on the bobbin so that there is a significant leakage inductance between the windings, the first and second tank windings having two discrete resonant frequencies on a common core and flux path, a main primary winding wound in series with the control winding, the main primary winding being wound onto a separate bobbin and residing on its own core leg and flux path, first and second secondary windings coupled with the main primary winding, the first and second secondary windings being wound out of phase with each other, the first and second secondary windings feeding, respectively, first and second diodes, the first and second diodes rectifying the alternately pulse current waveform generated by high-frequency operation of the inverter means.
