ABSTRACT:
A digitally controlled power system for controlling one or more power supplies having an output voltage including an analog to digital converter for sensing a difference between a reference voltage and the output voltage. Also included is a digitally controlled processor to provide a pair of control pulses to control the power supplies and a control memory to provide a program of instructions to said processor such that the processor provides a programmed change in the pulse width of the control pulses whereby the power supply provides a change in the output voltage.
