A performance comparison of interleaved boost converter and conventional boost converter for renewable energy application

Abstract

A performance comparison of an interleaved boost converter (IBC) and the conventional boost converter is presented in this paper. Also this paper investigates the performance of three-phase uncoupled and directly coupled Interleaved Boost Converter (IBC) for renewable energy applications. DC-DC Boost Converters serves many purposes. Low output voltage for renewable energy sources such as Fuel cells, Batteries, Photovoltaic cells. Interleaved Boost converter (IBC) has better performance characteristics when compared to a conventional boost converter due to its increased efficiency, reduction in size and greater reliability. IBC consists of a number of boost converters connected in parallel and controlled by the interleaved method which has the same switching frequency and phase shift. In this paper various parameters of the IBC are compared to a conventional boost converter.
