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 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 at their output. A transistor connection assembly comprising the plurality of power transistor modules connected in a plane and each having contact pads formed thereon for providing an output signal. A cross tie member is connected to four of the contact pads providing a combined output signal at a center point. The cross tie member comprises a sheet of rigid conducting material with width substantially greater than thickness and including four symmetrical arms extending outward from the center point. The design provides equal distance conduction paths for equal current sharing.
