Modified Coupled Inductor based Interleaved Boost Converter

Abstract

Boost converter exhibits voltage boosting ability as they deliver higher voltage level output from lower input voltage due to the temporarily storing of the input energy. The energy storage is done by either magnetic field storage units (single inductor/coupled inductor) or electric field storage units (capacitors) in addition to the use of various active or passive switches (power switches or diodes). There are various topologies and techniques for voltage boosting. In this study interleaved boost converter is modified by using it in conjunction with coupled inductor and voltage multiplier module. With modifications coupled inductor based interleaved boost converter topology can be used for industry, renewable energy and avionic applications. This modified boost converter has high gain, high power density and operates at a low switching frequency.
