ABSTRACT:
A method and apparatus used with a motor controller having a PWM inverter for eliminating discontinuities in a stator current that are caused by noise, command signal discontinuities and feedback corrections. While noise, discontinuities, and correction can cause multiple crossings between a carrier signal and a command signal during a half cycle of a carrier signal, the present invention only allows a single crossing during any carrier signal half cycle to effect motor operation.
