In this study, a new topology for single-phase five-level inverter is introduced. Operational principles of the proposed inverter are explained and operational topologies are respectively given. A method is improved for calculating switching angles. Simulation and experiment results are given to validate the rationality of this new inverter. The results of output voltage, load current and harmonic components of the output voltage are given and compared with a conventional H-Bridge Inverter to emphasize the advantage of the new inverter.
