A Strategy for Neutral Voltage Modulation Ensuring Fault Tolerance in CHB Multilevel Inverters With Reduced CMV and Unbalanced DC Sources

A Strategy for Neutral Voltage Modulation Ensuring Fault Tolerance in CHB Multilevel Inverters With Reduced CMV and Unbalanced DC Sources

This paper introduces a fault-tolerant control method for Cascaded H-Bridge Multilevel Inverters (CHB MLI) using Neutral Voltage Modulation (NVM), enabling reliable operation even when DC source modules are damaged or operating at reduced voltage. The method calculates the inverter’s modu...
