Keeping electrical systems running is critical in industries especially those that rely on static converters, for example the case of inverters, continuous and safe operation must be ensured even if one inverter’s switch modules fails. This paper presents a method fault detection converters. The study 3-phase 3-level NPC (Neutral Point Clamped) inverter with IGBTs as switches where open-circuit or closed-circuit faults are considered. In addition, leg failure structural reconfiguration also considered this fault-tolerant by adding fourth leg.
