A study of the basic DC-DC converters applied in maximum power point tracking

In maximum power point (MPP) applications the DC-DC tracker converter is as important as the MPP tracking algorithm. In this paper, the DC-DC Buck, Boost, Buck-Boost, Cu¿k, Sepic and Zeta converters are analyzed in order to determine which one is more proper to be applied as Maximum Power Point Tracker (MPPT). The proposed analysis take into account the radiation and temperature conditions, besides the load connected at the photovoltaic module. The comparison among the related converters is based in, both, analytical and simulation results.
