  • Push-pull DC-DC converter with transformer having multiple primary and secondary windings with diodes connected between them with MOSFET switching
    Patent number: 5886882
    Abstract: A converter has an assembly with a transformer primary and secondary windings and two pairs of primary and secondary choke windings wound around a core. Switching circuits are coupled between the transformer primary winding and the two primary choke windings. Each switching circuit has a capacitor, diode and a MOSFET. The MOSFETs are switched on and off in a cyclical manner to provide a continuous output current from a continuous input current by operating in a push-pull manner.
