Abstract
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. A housing includes at least one wall forming an enclosed perimeter, the wall including a plurality of fastener members extending therethrough. The power unit comprising a DC storage unit and DC bus and power switches connected with a heat exchanger provide signals to an AC bus wherein each is connected to each other to form a structural unit. The fastener members are connected through the wall and to the power unit for installation as a single unit in a vehicle.
