DRIVE December 19, 2019
Source
A vehicle includes an electric machine operated by an inverter. The electric machine includes a gate driver configured to energize a switch of the inverter with a pulse width modulation (PWM) signal. The gate driver is configured to delay the PWM signal by a dependent amount that is a function of a magnitude of current of a lead of the electric machine. The delay is responsive to a polarity of the current being positive.
