  • Switching power supply circuit including forward converter
    Patent number: 4736284
    Abstract: In a switching power supply circuit, a forward converter includes first to third switching transistors and a switching transformer having first and second primary windings. The first to third switching transistors are connected via series-connected first and second primary windings to a high voltage DC source. While the first to third transistors are simultaneously turned off, magnetic fluxes induced in the switching transformer are completely reset.
