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 wave form at their output. An Ac bus assembly comprises the power transistor modules connected in a plane and each having contact pads formed thereon for providing AC current sources. A bus bar interconnects at least one of the current sources to a peripheral device. The bus bar comprises a plurality of elongated flat plates having a width substantially greater than its thickness and laminated to one another.
