Solar-Fed Single-Input Three-Output DC–DC Converters for Low-Power Applications

Due to two significant benefits such as less voltage and high density of energy, the DC-to-DC converter has become very common today in the world’s electronic sector. The production of the DC-to-DC converter is therefore comparatively larger than that of normal AC-DC converters. The studies are developing multi-output DC-to-DC converters in latest years. These investigations focus on isolated as well as non-isolated DC-to-DC converters. A small input and output ripple sides, a minimum amount of switches, elevated voltage increase and lighter weight are the primary benefits of this type of converters. A single-input three-output SEPIC-Cuk-boost combination converter is analysed. It is working, and modelling and applications are also discussed. The solar panel used for the analysis is modelled by using its mathematical equations. Comparative studies of incremental conductance (IC) and Extended Perturb-Perturb (EPP) MPPT techniques are discussed for extracting highest power from the solar panel. The proposed solar-fed model is simulated by using MATLAB software. The experimental set-up of single-input to three-output SEPIC-Cuk-boost converter is developed, and the performance is compared with the simulated results. This proposed converter is able to generate two DC bipolar and one boosted DC output voltages.
