Converter as a Voltage Output Stabilizer for Wind Turbines

Abstract

Technological developments continue to increase every day. All human activities and actions always involve the use of electricity. Fluctuations in world oil prices have encouraged the emergence of various new innovations, so that many renewable energy sources have been discovered to replace fossil energy which is increasingly depleting. One renewable energy source that is widely known and is being developed is the Savonius Vertical Wind Turbine. This tool is a power generator that utilizes energy from the wind. To ensure the operation of the Savonius Vertical Wind Turbine, a battery with specifications of 12 Volt / 7.2 Ah is needed. One of the problems that arises is how to ensure that the voltage produced by the Savonius Vertical Wind Turbine matches the maximum voltage required to charge the battery. Based on this problem, the idea arose to design a SEPIC converter that could increase and decrease the DC voltage. This SEPIC converter is equipped with current and voltage sensors, so we can monitor the current flow coming out of the converter.
