New Various Cost Effective Cascaded H Bridge Asymmetrical Multilevel Inverter with reduced number of switches and DC sources For EV Applications

This study introduces a new cascaded multilayer inverter topology with a considerable reduction in switches and DC voltage sources. The suggested design is built on an asymmetrical MLI that uses 6, 8, and 10 bidirectional switches, as well as 2, 3, and 3 DC voltage sources, respectively, to create 5, 11, and 21 levels of output. The advantages of this topology include a reduction in the quantity of gate drive circuit, switches and DC sources. Additionally, the amount of money, space and complexity needed for the hardware is decreased without compromising the inverter's output quality. MATLAB/Simulink is used to simulate and verify the circuit in order to validate the suggested topology.
