Hybrid current regulation with a hard clocking and gentle clocking

摘要

A process for the regulation of a phase current of an electric motor is provided. The method, the selective activation of one or several switches each phase of the electric motor according to either of a motor control routine with gentle clocking, or a generation of routine with gentle clocking, the monitoring of the phase current relative to at least one limit of a hysteresis band, and a switching period, and the controlling the switch according to a routine with a hard clocking, when the phase current, the limit is not reached within the switching period have.
