一种具有集成开路故障容错功能的升压型四桥臂PMSM驱动逆变器

This article proposes a boost-type four-leg inverter for three-phase permanent magnet synchronous machine (PMSM) drives where the power supply is innovatively connected between the neutral point of the motor and the fourth leg. Due to the special connection, the zero-sequence circuit of a PMSM drive fed by the proposed four-leg inverter can not only be used to tolerate an open-phase fault (OPF) bu...
