Practical Implementation of A Modified Hybrid Bridge Multi-level Inverter

To reduce losses and expenses, multilevel inverter (MLI) researchers have recently been focused in minimizing the number of switches and providing the appropriate level of total harmonic distortion (THD %) of the output voltage waveform. In this paper, a single phase asymmetrical CHB-MLI that uses only 7 switches and 2 DC supplies to generate a 9- level output waveform was proposed as against the use of 16 switches and 4 DC supplies in a conventional CHB-MLI. The study was carried out using MATLAB Simulink; the inverter was also installed and operated in actual experiments. The results obtained from MATLAB Simulink were compared with the results of the actual experiments. The phase disposition pulse width modulation approach Which symbolizes (PD-PWM) as was used to control the suggested topology.
