Open-Circuit Fault Diagnosis of Clamping Diodes in Three-Level NPC Inverters Based on Phase Current Asymmetry Index

Eng
Three-level neutral-point-clamped (NPC) inverters are widely used in medium- and high-power drives and grid-connected applications due to their reduced device voltage stress, improved output power quality, and lower switching losses relative to ...
