Item Design and analysis of solar photovoltaic array fed modular full-bridge DC-DC converter for 12 kW SMPC(Institute of Electrical and Electronics Engineers Inc., 2018) P, P.S.; Kalpana, R.; Singh, B.This paper discusses the solar photovoltaic (SPV) array fed switched mode power converter (SMPC) using a modular full-bridge dc-dc converter as an intermediate converter. Among the different types of dc-dc converters, the straightforward and uncomplicated boost converter is selected in order to obtain the maximal power from the SPV array. The straightforward boost converter with reduced part count has inherent features of minimizing the output current ripples and possessing an unbounded region for maximum power point extraction. The improved efficiency of the converter is achieved by designing the SPV array to deliver maximum power at rated dc voltage and maximum switch utilization of the boost converter. The design, analysis and operating modes are explained for the proposed converter and the performance is validated through MATLAB/Simulink based simulation. © 2017 IEEE.Item Solar Photovoltaic Array fed Push-Pull Buck DC-DC Converter for Telecom Load(Institute of Electrical and Electronics Engineers Inc., 2018) P, P.; Kalpana, R.; Singh, B.This paper discusses the solar photovoltaic (SPV) array fed telecom load using modular push-pull buck dc-dc converter as an intermediate converter. The straightforward boost converter with lesser number of components and single switch device has inherent features of reducing the ripples in its output current. Also, the proposed front-end structure extracts maximum power in the boundless region. The SPV array is designed such that the power at rated dc voltage is supplied to the telecon load and maximum switch utilization of boost converter is achieved which results in improved efficiency of the converter. The design and analysis are carried out for the proposed converter and the performance of the proposed system is validated using MATLAB based simulation. © 2017 IEEE.
