Design and implementation of a new H-bridge multilevel inverter for 7-level symmetric with less number of switches

This paper proposed a new H-bridge of a higher output voltage level in multilevel inverters with reduce number of switches. This topology maintains the performance of a 7 levels output from multilevel inverter and reduction in switching losses, installation area, converter cost and size. The converter has a simple strategy switching control. The topology consists of 6 switches and two diodes for 4 mode operations. An output waveform is analyzed and the results obtained a better Total Harmonics Distortion (THD) compared to conventional method although the number of switches is reduced. The validity of the analysis has been proved by simulation and experimental results.
