Original Abstract Submitted
a system comprises an inverter configured to convert dc power from a battery to ac power to drive a motor, wherein the inverter includes: a galvanic isolator separating a high voltage area from a low voltage area; a low voltage phase controller in the low voltage area, the low voltage phase controller configured to receive a pulse width modulation (pwm) signal from an inverter controller and adjust the received pwm signal based on a feedback signal; and a high voltage phase controller in the high voltage area, the high voltage phase controller configured to receive the adjusted pwm signal from the low voltage phase controller, provide the adjusted pwm signal to a phase switch, and provide the feedback signal based on an on-time measurement of the phase switch.
