Abstract
Methods and apparatus for controlling a three-phase electric motor by determining a duration of current measurement windows within a first pulse width modulation period for measuring motor current using a single shunt coupled to the motor. A duration of a first one of the current measurement windows can be adjusted by a time delta value to meet a minimum time to measure the motor current. A next PWM period can include compensation for the time delta value. In embodiments window adjustments are made by modifying the high state of a middle phase signal for phase signals to switches that energize the motor.
