Abstract
A microprocessor based pulse-width modulated variable speed drive control system providing optimal switching angles based on minimizing r.m.s. current ripple. In addition, a closed loop double deadband control interacts with the optimal switching angles to insure close following of a desired function of a specified variable to be controlled.
