To realize the fault-tolerant control without adding extra hardware, a residual vector reconstruction strategy is proposed for an open-end winding motor drive system with isolated DC buses under the open-circuit fault of one switch. Meanwhile, the maximum utilization of residual voltage vectors is achieved, so that the operation performance of the drive system in its fault-tolerant operation is improved to a great extent. Furthermore, a phase duty cycle method is used to optimize the switching sequence in order to solve the problem of imbalanced switching action during the vector synthesis process. As a result, the switching action is balanced. Finally, the operation result under the proposed fault-tolerant strategy was analyzed in depth, and the operation performance of the system after fault was validated through a hardware-in-the-loop experiment.
