  • Active no-break power transfer control for a VSCF power generating system
    Patent number: 5317500
    Abstract: An improvement in a control for a DC link power converter includes a phase command signal generator responsive to DC power on a DC link wherein the phase command signal generator develops a phase command signal for a control of the power converter whereby a parameter the DC power is caused to approach a certain level.

  • Polyphase AC/DC converter
    Patent number: 5311419
    Abstract: A power converter for converting input AC power comprising N phase-to-phase input AC waveforms at a first frequency into overall output DC power, where N is an integer greater than two, includes N phase-to-phase AC/DC converters each receiving a phase-to-phase waveform and having outputs connected in series whereby the converter outputs are combined to develop the overall output DC power. The AC/DC converters are operated such that a parameter of the input AC power and a parameter of the overall output DC power are controlled.
