Abstract :
This paper presents a comparison between an analog compensated Sepic converter and a step down - step up converter (Buck-Boost) in a novel maximum power point tracking (MPPT) system. Both converters have advantages and disadvantages that will be pointed in this article. The algorithm that is used to provide the MPP for solar panels is Perturb and Observe (P&O) with three point weightings. Both simulations and practical results are analyzed and compared, afterwards conclusions are drawn.
