Abstract
A method and a converter for controlling a multi-phase electric machine are disclosed. Each phase voltage of the electric machine is generated with two electronic switches interconnected to form a half bridge. The switching statuses of the half bridges are controlled with space vector modulation. A minimum dwell time is predefined, and each switching status, represented by an active basic voltage space vector, of the half bridges is maintained at least for the minimum dwell time.
