摘要

Multilevel inverters have been attracting increasing interest recently, particularly because of the increased power ratings, improved harmonic performance and reduced electromagnetic interference (EMI) emission that can be achieved with the multiple dc levels that are available for synthesis of the output voltage waveforms. The two most common multilevel inverter topologies, shown in Fig. 1, are
