Abstract:

The decouple operating of double Y shift 30° PMSM series-connected system by a single inverter with the common DC supply and the common inverter can be achieved, which can save the control device and peripheral circuit and improve its reliability and reduces volume, weight and cost of the system. In this paper, the vector control strategy of double Y shift 30° PMSM series-connected system was proposed. The simulation mathematic model of the series-connected system was set up. The simulation research of variable load was pre. sented, which validates the feasibility of the series-connected system.
