Abstract
The level of demand for electrical energy in Indonesia is currently getting higher and will continue with the increase in population so that it is required to conduct research in the field of renewable energy. To be able to support renewable energy research, a switching circuit is needed for the battery charging system. The switching circuit used is a converter bidirectional circuit controlled by an Arduino Uno microcontroller based on PI (Proportional-Integral) control. PI control functions to regulate the voltage so that it has a stable output voltage value. From the research results of the Konverter bidirectional circuit, using trial and error control constants Kp: 2,6 and Ki: 5,6, it was found that the battery charging time was obtained with an initial voltage of 22.9 Volt to 24 Volt battery without using PI control, which was 6 hours 57 minutes, whereas if using the PI control with Kp: 2,6 and Ki: 5,6 with the initial battery voltage of 22.9 Volt to 24 Volt, the battery charging becomes faster, which is 2 hours 45 minutes.

Summary
Tingkat kebutuhan energi listrik di Indonesia saat ini semakin tinggi dan akan terus bertambah dengan perkembangan jumlah populasinya[1]. MetodeKonverter bidirectional berbasis Kontrol PI [11] sebagai pengatur daya pada turbin angin Permanent Magnet Synchronous Generator (PMSG) yang dapat bekerja dalam dua mode yaitu mode pengisian dan mode pengosongan, sehingga tegangan keluaran stabil [6]. Untuk mengetahui besaran komponen yang digunakan R14 dan R15 pada rangkaian sensor tegangan maka dapat menggunakan persamaan yaitu : Perhitungan Arus Maksimal Pada Beban Resistor. RangkaianKonverter bidirectional menggunakan input PWM dengan tujuan untuk mengatur duty cycle sehingga mendapatkan hasil yang maksimal dalam proses pengisian baterai. Untuk dapat menentukan nilai PWM yang akan digunakan, maka diperlukan sensor arus dan tegangan sebagai feedback ke mikrokontroler. Selama proses charging maupun discharging, sensor arus dan tegangan akan terus bekerja untuk memonitoring input dan output rangkaianKonverter bidirectional. Input dari sensor arus dan sensor tegangan akan diproses oleh Arduino Uno menggunakan metode Proportional Integral (PI) yang menghasilkan output tegangan yang stabil
