1. A system for a vehicle comprising:
a multiphase electric machine configured to orient a wheel associated with a rear axle of the vehicle; and
a first three terminal semiconductor switch configured to increase electrical conduction from one phase of the multiphase electric machine to another phase of the multiphase electric machine in response to a gate voltage of the first three terminal semiconductor switch being zero, and
the first three terminal semiconductor switch being configured to increase electrical resistance from the one phase of the multiphase electric machine to the other phase of the multiphase electric machine in response to the gate voltage of the first three terminal semiconductor switch being nonzero, wherein the nonzero gate voltage is negative with respect to a source voltage of the first three terminal semiconductor switch.
