  • Class E fixed frequency converter
    Patent number: 5065300
    Abstract: A two-stage, Class E, fixed frequency, resonant, DC-to-DC power converter employing phase-shift control achieves outstanding performance over a full range from no load to full load. Each stage of the DC-to-DC power converter comprises a series inductor-diode network in parallel with a feed choke. Such network is connected between a power source input and a switching transistor, and it provides a fast discharge path for a resonant capacitor and lossless turn-on of the switching transistor in each power converter stage.
