Space Vector Modulation with Flexible Switching Pause Period Function for Three-Phase PMSM Drive Inverters

This paper proposes a novel space vector modulation (SVM) method with flexible switching pause periods for three-phase permanent magnet synchronous motor (PMSM) drive inverters. The proposed method allows independent control of the switching pause periods for each of the six inverter switches. This flexibility enables accurate thermal management and loss distribution. By varying the switching pause period, the proposed method can adjust the losses of each switch. The experimental verification showed that the proposed method enables flexible switching pause periods for the six switches of the inverter under motor control.
