The conventional three-level T-type inverter (3L-T2I) can solve open-circuit fault (OCF) at any switching devices by itself. However, the conventional fault-tolerant (FT) methods for upper switch of ...

A new GTO current source inverter in which two auxiliary GTO's are added to the basic inverter circuit, which consists of six GTO's and three capacitors, is presented. One of the auxiliary GTO's is ...
