摘要
A method of regulating a phase current of an electric motor is provided. The method may include selectively enabling one or more switches of each phase of the electric motor according to one of at least a soft chopping motoring routine and a soft chopping generating routine, monitoring the phase current relative to at least one limit of a hysteresis band and a switching period, and controlling the switches according to a hard chopping routine when the phase current does not reach the limit within the switching period.
