SEPIC, DC-DC Konverter, Kendali Arus, Histerisis, Digital Signal ControllerAbstract
SEPIC (Single Ended Primary Inductance Converter) merupakan salah satu jenis konverter DC-DC yang digunakan pada peralatan dengan sumber DC untuk menaikan dan menurunkan tegangan. Konverter ini dapat dikendalikan dengan metode kendali arus loop tertutup histerisis. Arus referensi didapatkan dari pembangkit sinyal generator, sedangkan arus aktual dideteksi oleh sensor arus yang terhubung seri pada induktor. Selisih antara nilai arus referensi dan aktual menghasilkan nilai sinyal eror, sinyal ini kemudian dikendalikan menggunakan teknik kendali histeresis. Metode kendali histeresis ini pada prinsipnya adalah pengaturan nilai pita batas atas dan bawah untuk menentukan konduktivitas saklar statis pada konverter. Algoritma kendali histerisis ini diimplementasikan secara digital menggunakan 16-bit Digital Signal Controller. Dengan mengendalikan arus pada SEPIC konverter akan dihasilkan tegangan yang lebih besar dan lebih kecil pada keluaran konverter. Analisis, pemodelan, simulasi, implementasi perangkat keras dan pengujian laboratorium menunjukan teknik kendali arus ini menghasilkan unjuk kerja yang cukup baik.
