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 pump control system for pumping fluid through the heat exchanger includes a fluid pump, a control circuit connected to the fluid pump for operating same, and a power source having a nominal operating range and transients. The control circuit includes a shut off circuit for sensing power level on the power source and turning off the fluid pump when the transients are above a first predetermined level and turning on the fluid pump when the transients return below a second predetermined level.
