SPACE VECTOR MODULATION METHOD TAKING INTO ACCOUNT MINIMUM SWITCHING STATUS TIMES FOR CONTROLLING A MULTI-PHASE ELECTRIC MACHINE

摘要

The invention relates to a method and a converter (1) for controlling a multi-phase electric machine (3). Each phase voltage of the electric machine (3) is generated with two electronic switches (9, 10) interconnected to form a half bridge (5, 6, 7). The switching statuses of the half bridges (5, 6, 7) are controlled with space vector modulation, a minimum dwell time being predefined, and each switching status, represented by an active basic voltage space vector (15, 16, 17), of the half bridges (5, 6, 7) is maintained at least for the minimum dwell time.
