Multilevel Inverter for Higher Output Voltage Levels
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 12
Abstract
This paper presents the multilevel inverter for higher output voltage levels by using asymmetrical cascaded H-bridge multilevel inverter. The general function of the multilevel inverter is to synthesize a desired high voltage from several levels of dc voltages that can be batteries, fuel cells, etc. In this paper, the proposed hybrid cascaded multilevel inverters are suitable for high voltage and high current applications of industrial drives and FACTS etc., In general control methods of these cascaded inverters are designed an assumption of having all dc source voltages same for all H-bridges, but with different input voltage ratios. The optimal structures of this topology are investigated for various objectives, such as minimum number of switches minimum standing voltage on switches for producing maximum output voltage steps. The proposed topology results in reduction of the number of switches, losses, installation area, and converter cost. The operation and performance of the proposed multilevel converter has been verified by the simulation result of 7-level, 23-level, and 27-level inverter.
