Abstract

Saat ini pemanfaatan transfer daya nirkabel sudah semakin marak. Hal ini dikarenakan transfer daya nirkabel memiliki kelebihan dimana penggunaannya lebih mudah dikarenakan tidak perlu terjadi kontak secara langsung. Kelebihan ini dapat dimanfaatkan untuk mengisi daya mobile robot secara otomatis. Pada penelitian ini, telah dibuat suatu sistem transfer daya secara nirkabel yang diperuntukkan pada stasiun pengisian baterai. Sistem transfer daya yang telah terealisasi berupa prototype fungsional yang mampu mengisi daya baterai lead-acid 6 Volt dengan kapasitas 4,5 Ah. Metode transfer daya nirkabel yang digunakan adalah metode resonant inductive coupling yang dapat bekerja secara optimal pada frekuensi 91 kHz berdasarkan iterasi percobaan dari frekuensi 30 kHz-150 kHz. Pembangkitan listrik AC dengan frekuensi tersebut menggunakan H-Bridge yang dikontrol dengan microcontroller Teensy. Transfer daya nirkabel dapat berfungsi secara optimal pada jarak 20 cm. Pada sistem pengisian daya terdapat kontrol pengisian daya constant current-constant voltage (CC-CV). Dengan adanya metode kontrol CC-CV, maka diharapkan sistem dapat mengisi daya lebih cepat dan menjaga keawetan baterai lebih lama jika dibandingkan dengan metode kontrol CC atau CV saja. Pada penelitian ini parameter transfer daya nirkabel antara lain jenis rangkaian kompensasi, jarak, dan duty cycle dari sumber DC, telah diuji hingga didapatkan efisiensi mencapai 52 persen pada jarak sejauh 20 centimeter. ================= Nowadays, wireless power transfer is a growing demand in everyday life. Its convenience made it become a necessity to support another technology which require high degree of mobility such as mobile robot. A mobile robot which is designed to be autonomous in an outdoor area need to charge its battery periodically. With the absence of human operator, wireless power transfer can be a solution fto charge it. In this research, a prototype of wireless power transfer which could charge a 6 Volt lead acid battery with 4.5 Ah capacity is made. The wireless transfer method uses resonant inductive coupling to increase its efficiency over certain frequencies. The highest efficiency can be achieved at resonant frequencies which in this research is at 91 kHz.The 91 kHz AC waves are produced by an H-Bridge circuit which is controlled by Teensy, an ARM microcontroller. The prototype can transfer energy wirelessly through 20 cm air gap between transmitter and receiver with up to 52 percent efficiency. The battery charging system use constant current-constant voltage (CC-CV) method to accelerate charging time and preserve battery condition. In this research, several parameters are experimented to investigate the effect of compensation circuit, distance, and duty cycle of DC power source.
