The control strategy of the nine-switch converter for dual stator doubly salient electro-magnet driving system

This paper proposes a novel nine-switch converter for the dual stator Doubly Salient Electro-magnet Motor (DSEM) in the compact driving system. The dual stator windings are connected to the dual output ports of the proposed converter, and both the operation principle and normal commutation method for the proposed system are analyzed. The interaction of the coupled outputs of the nine-switch converter is analyzed and the advanced angle control (AAC) method is adopted to weaken the impact caused by the interaction. Finally, the simulation and experimental results demonstrate the feasibility and effectiveness of the proposed driving system.
