ABSTRACT:
A hybrid vehicle utilizes a power unit to store and convert power between a turbine alternator, flywheel and traction motor. The power unit includes a water cooled heater exchanger for cooling power transistors used to switch stored and generated power between the peripheral machines. A power supply for a plurality of an isolated transistor drives comprises a chopped DC generator producing a chopped power signal, a plurality of gate drives each including a transformer to receive the power signal and electrically isolate the gate drives, one of the transformers providing feedback to the chopped DC generator for regulating the level of the chopped power signal. A plurality of power transistors are connected in parallel and includes a controller providing a drive signal. A plurality of optical isolators receive the drive signal in series to control the power transistors independently.
