A Single-Phase Symmetric Cascaded Multilevel Voltage Source Inverter With Reduced Number of Requirements

In this paper, an advanced configuration for symmetric multilevel voltage source inverter is proposed. Owing to the lower number of circuit devices needed, the overall cost, circuit size and so installation area, complexity of control scheme are reduced considerably and the reliability is enhanced as well. The provided comparison study among suggested inverter, CHB and the recently proposed converters, validates that the proposed modular inverter uses reduced number of power semi-conductor switches, gate driver circuits and DC voltage sources. The given simulation results confirms the feasibility of the proposed configuration. Also, to approve the practicability of the proposed inverter, a prototype of the proposed topology has been implemented. Finally simulation and experimental results are compared with each other and the provided comparison shows that the obtained results are in good agreements.
