ABSTRACT:
A hybrid vehicle includes a power unit communicating power between a turbine alternator, flywheel and traction motor. The power unit stores DC power in capacitors and places the power on a DC bus for use in driving the induction machines. Power transistors receive the DC power from the DC bus and are pulse width modulated to output a synthesized AC waveform. The power transistors include a support plate of thermally conductive material having a first surface supporting the transistor and a second surface forming a heat sink with cooling fluid. An electrical insulation layer is fixedly connected between the power transistor and the support plate on the first surface.
