Title: Method and apparatus for improved efficiency in a pulse-width-modulated alternating current motor drive

Abstract

A scheme for optimizing the efficiency of an AC motor drive operated in a pulse-width-modulated mode provides that the modulation frequency of the power furnished to the motor is a function of commanded motor torque and is higher at lower torque requirements than at higher torque requirements. 6 figs.
