ABSTRACT
This research paper of asymmetric multilevel converter describes about the new structure that can produce increased number of output voltage waveform using a single source and reduced number of power electronic components. In designing a multilevel converter, the power electronic switches play a very imperative role as it describes the installation area, cost, configuration complexity and may more things that play a significant role while designing. The prime function of multilevel converter is to abolish total harmonic distortion and to incorporate desired ac voltage from several separate dc sources. Each level consists of H-Bridge converter units. High efficiency, high voltage capability, lower switching losses are its prime advantages. 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).
