Perspective of Voltage-Fed Single-Phase Multilevel DC-AC Inverters

Standing out for their remarkable benefits, such as lower voltage stress on integrated semiconductor devices, reduction in total harmonic distortion, well electromagnetic effects, multilevel inverters (MLIs) increase share the field of energy supply. The inverter is an interesting research topic that realizes generation desired output waveforms composed small steps. However, many studies have put a premium structure, efficiency, and inverter, but there are relatively few THD practical product applications. Consequently, this brief perspective, some puzzles MLIs pointed to explore new ideas present questions.
