A New Cross Switched Cascaded Multilevel Inverter Topology with Reduced Number of Switches

For clean and economical energy, renewable energy resources are widely used for providing electric supply to the consumers. But renewable resources produce dc supply, so multilevel inverters are required for conversion from dc to ac supply as the output voltage generated by multilevel inverters contain less harmonics as compared to conventional two level inverters. In this paper, a new asymmetrical multilevel inverter topology is proposed which generates the maximum output voltage using cross over switches. This topology requires less number of voltage sources, power electronic switches and driver circuits as compared to the conventional multilevel inverter topologies. In addition, proposed topology utilise the dc voltage sources amplitude in such a way so that all the possible levels will be generated in output voltage. The performance and operation of the proposed topology is verified using simulation in MATLAB environment. Various waveform and simulation results are presented to validate the performance of proposed topology.
