Implementation of Twenty seven level and Fifty one level Inverter using constant voltage sources

摘要

A inverter to produce more output voltage levels using constant voltage sources fed to a resistive-inductive load is presented. Cascaded multilevel inverter structure is modeled and studied for various levels of voltages by implementing proper turn on and turn off states. Simulation for fifty one level inverter design structure is carried out using MATrix LABoratory and percentage of harmonic content in the load voltage is examined. Further, real time development of twenty seven level cascaded inverter structures is implemented and the results are obtained using digital storage oscilloscope. A 15V, 500mA transformers are used to step down the voltage from 230V to 15V and further rectifiers are used to convert AC to DC voltage and used as source for multilevel inverter structure and field programmable gated array.
