Abstract: Systems, apparatus and methods are presented for multiphase inverter control in which PWM switching control signals are generated for operating inverter switching devices according to current feedback values, and a given inverter phase is identified in a given PWM switching cycle having the lowest low side duty cycle on-time. A phase current feedback value is selectively computed for the identified phase at least partially according to the low side current shunt voltage values corresponding to other output phases, and the phase current feedback values are updated with the computed phase current feedback value and the low side current shunt voltage values of the remaining output phases to provide feedback for closed loop PWM switching control.
