Abstract : This paper shows a novel hybrid Multilevel inverter configuration with less number of power electronics (8 IGBT) switches and 4 dc-link voltage source can be modified with 7 level based model (6 switeches and 2 dc sources) series connected with half h-bride to produced output voltage 21-levels, which is nesar to sinusoidal. The carrier-based level shifted PWM (LSPWM) switching pulses method are used. The proposed MLI is finally verified with the MATLAB/SIMULINK platform and developed to prototype hardware setup with RL load with symmetrical and asymmetrical configuration. In addition, the corresponding experimental results are demonstrated for the different values of modulation index with real time dspace ds1103.
