Abstract
This paper deals with asymmetric multilevel converter with a single source that can produce greater amount of output voltage waveforms with a reduced number of power electronic components. The power electronic switches play a very important role in designing a multilevel converter because they define the cost, installation area, circuit size and complexity. MOSFETs are used as switches. The existing system of asymmetric cascade topology significantly increases the number of output voltage levels. The main function of multilevel converter is to remove total harmonic distortion and to synthesize desired ac voltage from several separate dc sources. Each level consists of Hbridge converter units. It has the advantage of high efficiency, high voltage capability, lower switching losses, etc. A multilevel power converter structure can be introduced as an alternative in medium voltage and high power situations. This structure not only achieves high power ratings but also empower the use of renewable energy sources. It finds its basic application in adjustable speed drives, Static Var Compensator (STATCOM).
