Abstract
Battery charger merupakan alat yang digunakan untuk charging baterai. Battery charger dalam penelitian ini menggunakan model buck converter. Perancangan battery charger ini menggunakan sistem daur-tertutup dengan pengendali PI untuk mengatur arus yang masuk ke baterai. Pengendali daur-tertutup digunakan untuk mengatur tegangan dan arus sesuai metode charging baterai CCCV dengan memanipulasi sinyal PWM. Nilai rata-rata tegangan keluaran sebanding dengan rasio antara waktu penutupan saklar dengan periodenya (duty cycle). Battery charger menggunakan tegangan input 24V sebagai sumber catu daya untuk charging baterai 12V dengan mengatur arus yang masuk ke baterai sebesar 1A. Hasil simulasi dengan perangkat lunak Power Simulator (PSIM) menunjukkan bahwa dengan menggunakan pengendali PI, battery charger mampu memberikan suplai arus konstan sesuai set point untuk charging baterai. Nilai konstanta PI diperoleh dengan metode trial and error dengan nilai Kp = 0.025 dan Ki = 0.3. melalui uji coba rangkaian, diperoleh hasil bahwa nilai ripple arus sebesar 0.18 A dimana nilai tersebut tidak melebihi nilai ripple yang diperbolehkan dan error steady state sebesar 1%

Battery charger is a tool used for battery charging. Battery charger In this study uses the buck converter model. The design of the battery charger uses a feedback system with an PI controller to regulate the current into the battery. The feedback controllers are used to regulate the voltage and current according to the CCCV battery charging method by manipulating PWM signals. The average output voltage value is comparable to the ratio between the switch on and period usually known as duty cycle. The battery charger uses a 24V input voltage as a power supply source for the 12V battery charging by regulating the current that goes into the battery of 1A. Simulated results with the Power Simulator software (PSIM) indicates that using the PI controller, the battery charger is able to provide a constant current supply of a set of points for battery charging. Values of PI constants are obtained by trial and error method with gain Kp = 0.025 and Ki = 0.3. Through circuit trials, obtained the result that the current ripple value of 0.18 A where the value does not exceed the allowed ripple value and a steady state error of 1%.
