  • Resonant-boost-input three-phase power factor corrector with a low current stress on switches
    Patent number: 6239995
    Abstract: A three phase AC-DC power conversion circuit is provided. The circuit includes a plurality of input inductors and capacitors and output capacitors. A high frequency current source is operably connected between the input and output of the circuit and operates to transfer energy from the input capacitors to the output capacitors. The energy is transferred through the secondary of a transformer in the high frequency current source. Current in the high frequency current source's switches flows through the primary of the transformer.
