A matrix converter for fault tolerant strategies and two-phase machine drives

Novel control schemes for continuous, fault-tolerant operations of matrix converters are presented. The proposed algorithms based on both Venturini method and SVM method can be applied to the indirect matrix converter as well as the conventional matrix converter topologies. By initiating the proposed control schemes in the event of fault occurrence, continuous and disturbance-free operation can be obtained. The control methods for two-phase motor drives are also presented with minor modification. Theoretical analyses and the derivation of computational relations are described using two modulation methods. Simulation results are provided to verify their feasibilities.
