Abstract: TWELVE-PHASE rectification obtained by connecting two double-way rectifiers in series on the d-c side is often employed in special applications requiring high direct voltages. The customary ...

Abstract: Dual three-phase permanent-magnet synchronous machines (DTP-PMSM) connected with a single neutral point provide a loop for zero-sequence current (ZSC). This paper proposes a novel space ...
