Modeling and experimental validation of 5-level hybrid H-bridge multilevel inverter fed DTC-IM drive

This paper aims to improve the performance of conventional direct torque control (DTC) drives proposed by Takahashi by extending the idea for 5-level inverter. Hybrid cascaded H-bridge topology is used to achieve inverter voltage vector composed of 5-level of voltage. Although DTC is very popular fo...
