【 摘 要 】

Indonesia is an archipelago and one country located on the equator with abundant wind energy potential. Various studies of wind turbine models are used to study electric power systems. This development is based on various research focuses such as turbine propellers, wind speed, and electrical charging coefficients. So that in this study there is a need to design a charger controller to charge a 6 Volt battery load, 4.5 Ah on the axial axis mini wind turbine type plant. In this charger contoller circuit is composed of 2 circuits namely the boost converter circuit using a 3.2 mH inductor and power IRFP460 MOSFET and pulse signal generator range PWM (Pulse With Modulation) and 4N35 Optocoupler IC and ARM CORTEX M0-NUC 120 Microcontroller. The method used is through preliminary observation, problem identification, literature study and field studies, determining parameters and data collection. From the results of the charger controller trial results obtained an average output voltage of this controller is 6 volts, which has adjusted the voltage specifications to charge the 6 volt battery and the resulting current is an average of 0.02 amperes. With a frequency of 1.25 KHz and a duty cycle of 70%. The highest charger controller efficiency occurs at 7 m/s wind speed with an efficiency value of 3%. The design of the charge controller that has been made for the output voltage of the DC 1-4V generator which will be increased by the boost converter with the input voltage value of 6-7 volts to meet the charge voltage for the battery battery 6V, 4.5Ah, the output variable of the generator DC is controlled by the charge controller using the switching method. The battery charging control system using this auto cut off circuit works when the Depth of Discharge voltage of the 6 V battery is 50% at a measured voltage of 6.12 V and the charging process stops when the voltage reaches 6.05 V.
