Desain dan Simulasi Battery Charger Metode CC-CV (Constant Current-Constant Voltage) dengan Kontrol Logika Fuzzy Menggunakan MATLAB

Abstract: Baterai merupakan salah satu sistem penyimpanan energi listrik. Namun, dalam pengisiannya rentan mengalami kerusakan. Kerusakan pada baterai sering terjadi ketika dilakukan pengisian daya yang berlebih (over charging). Waktu pengisian baterai juga menjadi faktor yang perlu diperhatikan dalam pengisian daya. Oleh karena itu, pengisian daya baterai yang efisien menjadi penting dan sangat perlu dilakukan untuk menghindari terjadinya kerusakan. Sistem charging pada baterai disini dengan metode constant current-con… Show more

“…This fuzzy logic method will produce an output in the form of a duty cycle, which is used to regulate PWM generation on the interleaved buck-boost converter so that the voltage and current for charging the battery are generated according to the set point value. There are two fuzzy input variables, namely error and delta [19]. Membership function for input error and delta error used in research is divided into 7 parts, each consisting of Negative Big (NB), Negative Medium (NM), Negative Small (NS), Zero (Z), Positive Small (PS), Positive Medium (PM), and Positive Big (PB) [18].…”

“…9 has the same mapping as the input, but uses a singleton function, which is a membership function that has a membership value of 1 for a single actual function and 0 for another actual function. At the fuzzy inference system stage, the fuzzy input results from the fuzzification process then will be interpreted by considering the specified rule base [19]. This project uses the Sugeno type of inference.…”

“…Kontrol Fuzzy digunakan sebagai keandalan pengisian baterai dan keamanan operasi beban DC [14]. Pada perancangan fuzzy terdapat beberapa tahap yaitu fuzzification, inference, defuzzification [15]. Secara umum bagian dari fuzzy adalah masukan algoritma fuzzy berupa E (error) dan ΔE (delta error).…”

“…Dan nilai delta error diperoleh dari selisih antara nilai error saat ini dengan error sebelumnya. Pada persamaan (10) 3) Defuzzifikasi: Pada proses ini nilai fuzzy output dikembalikan menjadi data keluaran tegas (crisp output) [15]. Pada tahap deffuzifikasi ini menggunakan metode weight average, pada metode ini mengambil nilai ratarata dengan menggunakan pembobotan berupa derajat keanggotaan, seperti pada persamaan ( 12).…”
