## 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.

## Claims

### Claim 1

A power supply for a plurality of isolated transistor drives comprising:
a chopped DC generator producing a chopped power signal;
a plurality of gate drives each including a transformer to receive said chopped power signal and electrically isolate said gate drives;
one of said transformers providing feedback to said chopped DC generator for regulating the level of said chopped power signal; and
a load connected in the feedback to simulate a load formed by said gate drives.

### Claim 2 (depends on 1)

A supply as set forth in claim 1 wherein said generator includes a step down regulator for supplying a DC voltage at a regulated level based on the feedback.

### Claim 3 (depends on 2)

A supply as set forth in claim 2 wherein said generator includes a pair of half transistor bridges and a pair of charging capacitors to sequentially form the pulses of the chopped power signal.
