The requirement of high-voltage, high-power converters capable of producing high-quality waveforms forced the development of power switching and reduced switching frequency devices and equipments. Multilevel inverters proved itself as a vital utility with regard to semiconductor power switch voltage limit barriers. Presently research is ongoing to improve their capabilities further through optimized control techniques, and to minimize both component count and manufacturing cost. Owing to voltage limits power switches are typically cascaded in series and configured as multilevel structures.
