Modulation strategy for new asymmetrical multilevel inverter topology using nearest dc level modulation technique

Multilevel inverters (MLI) have an important portion in power processing in power systems. These inverters have some inherent advantages such as ability to operate with high power and voltage, improved output waveform quality, and flexibility, which make them attractive and more popular. In recent y...
