针对中点电压不平衡调制的T型三电平变换器主动容错控制

The rectifier and inverter in the T-type back-to-back converter are interconnected via a capacitance with a dc-link midpoint. Faults in the inverter switches of the converter will result in current distortion, load power loss, and dc voltage unbalance, which subsequently impact rectifier operation and grid power quality. While many studies have focused on achieving complete inner switch fault tole...
