The widespread use of electric drives has led to an increasing interest in their condition monitoring and fault diagnostics. With respect to power-switch open-circuit fault diagnosis, the majority of the proposed voltage-based approaches require additional hardware, increasing the system cost. As a result, industry acceptance may be low. This paper proposes a new voltage-based approach—without additional...
This paper presents a fault-tolerant converter intended for AC regenerative drives requiring improved reliability and availability. The standard six-switch three-phase converter is rearranged in order to obtain a four-switch tree-phase converter (FSTPC) during post-fault operation. Thus, its performance relies heavily on the fault diagnostic technique to trigger the remedial procedures, and on the...
