Abstract
Photo-Voltaic application basically converts direct sunlight into electricity without causing any harmful environmental pollution and any moving parts. These are superior in comparison to the conventional sources like fossil fuels to satisfy world's energy demands and so has a wide variety of applications. Different DC-DC converter topologies have been proposed in the literature but Interleaved Boost Converter (IBC) is widely used for photovoltaic generation due to its high power density and fast dynamic response. This paper presents a comparative study of conventional, coupled inductor and Ripple Cancellation Network (RCN) based IBC for photo-voltaic applications. IBC is more efficient than a conventional boost converter as it reduces the input current ripple, output voltage ripple and the component size and improves the transient response. Adding the Ripple Cancellation Network to the conventional IBC converter, minimizes the input current and output voltage ripple. The parameters that will help us decide the performance of the proposed converters are input current ripple and output voltage ripple. Simulation studies are carried out in MATLAB to verify the theoretical results.
