Multilevel voltage - source inverters are the best solution for high power dc - to - ac conversion applications. A multilevel inverter is a linkage structure of multiple input dc levels and power semiconductor devices to get a quasisquare waveform . In addition,the multilevel waveform has less harmonic contents as compared to a two - level waveform obtained from conventional inverters. The quality of the multilevel waveform is improved by increasing the number of levels. But,if number of level increases,a large number of power semiconductor devices and gate driver circuits are also increased. So,it will increases system complexity and cost and tends to reduce the system reliability and efficiency. For a high - resolution waveform,therefore,...
