(JP9117141-A)      The converter (100) includes a transformer section and a choke. It also has a core and primary and secondary windings. The primary circuit includes a switching circuit which is coupled between one primary choke winding and a primary transformer winding. A second switching circuit is coupled between the primary transformer winding and the second primary choke winding.    The two switching circuits operate in a push-pull manner throughout a switching cycle. A flux flow in the transformer assembly is such that a voltage induced in the secondary windings provides a continuous output voltage and current throughout the cycle.    ADVANTAGE -   Increased efficiency due to use of fewer components. Allows twice normal flux excursion. Reduced ripple due to avoiding use of capacitor.
