ABSTRACT:
A power converter is provided with a split primary current fed push pull topology. An inductor connects the primary windings. Controllable switches provide alternate circuits from the dc source inputs through each of the primary windings and the inductor. Clamping diodes connect the ends of the inductor to the dc source inputs opposite to those provided by the controllable switches. The clamping makes cross conduction unnecessary. Separate duty cycle control is provided in each primary circuit.
