Closed Loop Contol of ZCS Interleaved High Step Up Converter for Sustainable Energy Applications

Maria T Kuriyakose | Aswathy Rajan

Abstract: The Renewable energy is the best solution to satisfy the energy shortage without environmental problems. Photovoltaic energy is the most promising energy among the renewable energies. The main advantages includes long life and maintenance free and the main disadvantages are high installation cost and low conversion efficiency. The narrow turn off period of the conventional interleaved boost converter limits its application for high step-up applications. The interleaved boost converter with built in transformer voltage multiplier cells overcomes this drawback. This converter provides an additional control freedom to achieve extremely high voltage conversion ratio and minimize the ripple current. Additional advantages are switch voltage stress and conduction losses are also reduced. To study the performance of the high step up Interleaved DC-DC converter with closed loop control, simulations has been carried out in MATLAB2013 environment. Thus these current and voltage waveforms agreed with the operating principles and the steady-state analysis.
