A hybrid cascaded multilevel inverter with PWM method is presented in this paper. It consists of a standard 3 - leg inverter (one leg for each phase) and H - bridge in series with each inverter leg. It can use only a single DC power source to supply a standard 3 - leg inverter along with three full H - bridges supplied by capacitors . Multilevel carrier - based PWM method is used to produce a five - level phase voltage . The inverter can be used in hybrid electric vehicles ( HEV) and electric vehicles (EV). A simulation model based on PSIM and MATLAB/SIMULINK is developed. An experimental 5 kW prototype inverter is built and tested. The results experimentally validate the proposed PWM hybrid cascaded multilevel inverter.
