Design of Medium Voltage Cascaded H Bridge Multilevel Inverter with Reliability Consideration, M.Sc. Thesis Sharif University of Technology ; Zolghadri, Mohammad Reza (Supervisor)
Abstract
Today, with the development of power electronics and the emergence of various multilevel converters, possibility of operation at the voltage and powers higher than the rated value of components is provided. The reliability of these converters due to their high power is important. In this project, design of multilevel inverter with cascaded H-bridge structure have been studied for a medium voltage and high power 3.3 KV, 1MVA application, due to its advantages over other structures. This converter is composed of several cascaded low voltage full-bridge cells. Therefore, the converter is composed of many semiconductor elements that the reliability of them depends on the physical stresses such...
