| Abstract | ||||
| This paper presents a modified multilevel inverter with a few number of semiconductor switches and increasing number of output levels. One stage of the proposed inverter leads to get seven levels in the output voltage, while, forty-nine levels can be obtained when using two stages. Only six semiconductor switches are required for each stage. Standard DC sources are used, so, DC-DC converter is not required to get the desired output standard voltage. Total harmonic distortion in the output waveform of the two stage inverter is very low, so, using filter to improve output waveform is unnecessary. This topology is valid for all types of loads. Simulation results are presented for one stage and two stage inverters proposed. Experimental results are included for the one stage inverter to verify the theoretical results. | ||||
