ABSTRACT:
The power supply of the present invention simultaneously provides multiple regulated power outputs for the digital circuitry within CRT terminals and a stable current sawtooth waveform suitable for driving a magnetic deflection yoke. The power supply comprises a high voltage transformer connected to a horizontal yoke to drive the CRT beam and a low voltage transformer which drives a microprocessor, communication circuitry, and the various other components of the power supply circuit. There is only one set of control switching, start up and protection components that drive the high voltage and low voltage transformers. The power supply provides a horizontal sync signal which is always locked onto the CRT monitor and also provides a steady voltage output to drive the CRT microprocessor.
