Fault analysis in the 5-level multilevel NCA DC–AC converter

open access: yesAutomatika, 2023
The existing neutral clamped active inverter has common mode voltage with the high frequency which can reduce the severity with less voltage gain. The traditional active neutral point clamped (APC) DC–AC converter maintains great common mode voltage with
