A Novel Three-Phase Three-Level Inverter with Asymmetrical Legs

Abstract:

A novel three-phase three-level inverter circuit with asymmetrical legs is proposed. The new prototype is very effective and efficient for improving the quality of the inverter output voltage. Firstly, the structural parts of the inverter are briefly described, then switching strategy and operational principles of the proposed inverter are explained and operational topologies are given. The proposed topology reduces the number of switches, losses, installation area and converter cost. Finally, the simulation and experimental results are provided to validate the effectiveness and advantages of the proposed configuration.
