New Converter Circuitry for High Voltage Applications Using Switched Inductor Multilevel Converter Mostafa Mousa, IEEE Student Member, Mahrous E. Ahmed, IEEE Member, and Mohamed Orabi, IEEE Senior Member, APEARC, Aswan Faculty of Engineering, South Valley University, Egypt [email protected]

Abstract- This paper presents an analysis and design of a high voltage gain DC-DC converter. This converter is a single stage DC-DC multilevel boost converter

topology

with very large

voltage gain conversion ratio. It is called a Switched Inductor Multilevel Boost Converter (SIMLBC). It converts a low voltage

converter is the efficiency because there are a lot of components that consume power. So this work investigates practical circuit
