A Novel Wind Energy Integration and MPPT Algorithm based Multi-Input Multi-Output DC DC Converter

This study presents the development of a high-efficiency multi-input multi-output (MIMO) DC/DC converter integrated with wind energy and a wind maximum power point tracking (MPPT) algorithm for renewable energy applications. In renewable energy systems, particularly those utilizing wind power, multiple output voltages are often required to power various loads, while optimizing energy conversion efficiency. The proposed MIMO DC/DC converter accommodates multiple input sources, including wind turbines, while achieving high step-up voltage conversion to provide stable output voltages for different applications. The converter utilizes a coupled inductor with a low turn ratio to enhance voltage gain, while the MPPT algorithm ensures maximum power extraction from the wind turbine by continuously adjusting to the changing wind conditions. The converter employs soft-switching techniques, including voltage clamping and zero-voltage switching (ZVS), to improve efficiency by reducing switching losses. Additionally, an auxiliary inductor regulates the voltage of the auxiliary output, enabling effective energy management across multiple outputs. Experimental results validate the high efficiency and performance of the proposed converter, demonstrating its suitability for wind power generation and other renewable energy systems requiring multi-output configurations.
