Abstract
The invention provides a laser gyro with a single transformer power supply. The power supply receives a single 15 volt DC supply that is converted to a 320 volt DC supply, a 280 volt DC supply and a 500 volt DC supply. The invention implements a Royer Oscillator by providing a transformer with four windings each center-tapped. Two control transistors control the output of the transformer. The invention also provides a high speed output controlled start-up to prevent meta-stability in the Royer Oscillator.
