Ali Mahmood Jasim

Abstract


The increasing of  efficiency of the satellite electrical power supply system (PSS) is important engineering task. Modern satellite PSS widely use DC-DC converters under pulse-width controlling. Existing methods of maximum power point tracking of such systems not always can  to search surely for maximum power point if there are existing  some local maximums of power. It can be if illumination of few non-oriented solar panels are different. This paper present the modeling of modified hill climbing (HC) maximum power point tracking (MPPT). The aspect of the method is choosing initial point through open circuit voltage coefficient and next tracking by using of special function through digital differentiation of measured values of output power with scaling on actual power and special empirical coefficient. The simulation results revealed robust tracking of the main peak power at a sufficiently rapid convergence.
