Maximum power point tracker for a multiple-input Ćuk dc-dc converter

Photovoltaic modules require a maximum power point tracker in order to achieve maximum conversion efficiency when the maximum power point changes based on solar irradiance, temperature, cells age, and other factors. The need to track the maximum power point while combining multiple-input sources has stimulated research on maximum power point trackers for multiple input dc-dc converters. When compared to prior work, a multiple-input Ćuk dc-dc converter seems to be an adequate choice when combining PV modules with alternative energy sources, such as fuel cells, because it provides current source interface and is capable of stepping up and down input voltages. This paper proposes a multiple-input Ćuk dc-dc converter topology. Ripple correlation control is used to find the maximum power point of a photovoltaic array.
