| Summary: | 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. |
