A new structure of multilevel inverters based on coupled inductors to increase the output current

Due to some key features of multilevel inverters, these types of power electronic converters have attracted intensive attention. In this paper, a new topology is proposed for multilevel inverter. The proposed topology is based on using coupled inductors. As a result of using coupled inductors, the output current is increased while the currents through the power electronic switches are less than output current. This is not the case in the most of the existing topologies. This structure can be considered as the perfect solution to reduce the nominal values of switches and increase the output current. Simulations results of the proposed topology in single-phase scheme using the PSCAD/EMTDC software are presented to verify its operation.
