Abstract

The objective of this paper is to propose a multi-input interleaved boost converter for hybrid renewable energy system in order to design high efficiency and high performance converters for renewable energy applications. DC-DC Boost Converters serves many purposes and usually required in many applications which has a low output voltage for renewable energy sources such as Fuel cells, Batteries, Photo-voltaic 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 hybrid renewable energy applications, interleaved operation of two or more boost converters with one input source has been proposed to increase the output power and to reduce the output ripple. A major design criterion then is to ensure equal current sharing among the parallel converters. This paper focuses on the design aspects of two phase interleaved boost converter interfaced with multi input converter. The operating principle, steady-state analysis, and comparison with the conventional multi input source converter are presented. Simulations of interleaved boost converter interfaced with multi input source have been performed using MATLAB/SIMULINK .Theoretical analysis is done to emphasis the benefits of the interleaved method interfaced with multi input source converter and simulation results are also given.
