The need for high power apparatus in industry has increased in recent years. Multilevel inverters have developed as easy alternatives for such power requirements. Multilevel inverters consist of a group of semiconductor switches and a set of voltage source components like capacitors or independent sources. The basic concept of these inverters depends on using this series of switches and sources...
