Abstract:
A vehicle power system includes a controller configured to issue commands to open a selected set of switches of an inverter and then to operate the selected set of switches according to a pulse width modulation signal having an increasing duty cycle such that input current to a battery is driven towards zero and a magnitude of d-axis current of the drive system is reduced in response to a fault with an electric drive system.
