The three-phase series-end winding motor drive (SWMD), which connects the three-phase windings in series with identical polarity, is attracting attention due to excellent drive performance. However, when the fault occurs on the center bridges that are multiplexed, smooth torque output capability cannot be obtained anymore, which narrow the applications of SWMD for high reliability requirement. This paper proposes a SWMD with new connection mode of phase windings. Without extra hardware expense, the proposed topology can tolerant the open-circuit of the multiplexing bridge, which greatly improve the reliability of drive system. Experimental results are presented to verify the fault tolerance of the topology.
