A power converter that can be used either as a start converter or as a variabe speed constant frequency converter is utilized within a stepped waveform VSCF system having engine start capability. Interfacing with the converter are a load bus, a contactor, a field excitation controller and a starter/generator having a main generator, an exciter generator and a permanent magnet generator. Magnetic components and semiconductor components perform multi-functions and minimal degradation of input power quality occurs.
A stepped waveform VSCF system with engine start capability comprising: starter/generator means mounted to an engine; converter means connected to said starter/generator means and including a plurality of DC/AC inverters connected to said starter/generator means, a plurality of high frequency trap-tuned filters connected to contactor means, three phase transformer means connected between said plurality of high frequency trap-tuned filters and said plurality of DC/AC inverters for providing isolation, and filter capacitor means connected across said plura...
