Abstract

The use of cables in smartphone charging often presents several problems, such as limited mobility, cable damage, and reliance on physical connectors. This has led to the development of alternative charging technologies that are more practical and flexible. This research aims to address these issues by designing and testing a Wireless Power Transfer (WPT) system based on electromagnetic induction for wireless charging applications. The system was designed by building two main circuits: the transmitter and the receiver. The transmitter circuit generates alternating current through a switching process using an Arduino Uno microcontroller, IR2101 driver, and IRF3205 MOSFETs, which then flows through a transmitting coil to produce an electromagnetic field. The energy is transferred through the air and captured by a receiving coil, then converted into DC voltage through a rectifier and filter circuit. Each block of the system was tested to ensure functionality and to measure the output voltage on the receiver side. The test results showed that the system successfully transmitted electrical energy wirelessly, with the highest output voltage recorded at 8.53 V, and another configuration producing 5.12 V, in line with the system's design target. All processes have undergone thorough measurements across the generation, driver, and receiver stages. Therefore, the device has successfully addressed the initial problem of cable-free charging and operated in accordance with the research objectives. Keywords: Wireless Power Transfer, Electromagnetic Induction, Coil, Arduino Uno, MOSFET IRF3205 Penggunaan kabel dalam proses pengisian daya smartphone sering menimbulkan berbagai kendala, seperti keterbatasan ruang gerak, risiko kerusakan pada kabel, dan ketergantungan pada konektor fisik. Hal ini mendorong pengembangan teknologi pengisian daya alternatif yang lebih praktis dan fleksibel. Penelitian ini dilakukan untuk menjawab permasalahan tersebut dengan merancang dan menguji sistem Wireless Power Transfer (WPT) berbasis induksi elektromagnetik untuk pengisian daya secara nirkabel. Perancangan sistem dilakukan dengan membangun dua rangkaian utama, yaitu pemancar dan penerima. Rangkaian pemancar menghasilkan arus bolak-balik melalui proses switching berbasis mikrokontroler Arduino Uno, driver IR2101, dan MOSFET IRF3205, yang kemudian dialirkan ke kumparan pengirim untuk membentuk medan elektromagnetik. Energi ditransfer melalui udara dan ditangkap oleh kumparan penerima, lalu diubah menjadi tegangan DC melalui rangkaian penyearah dan filter. Pengujian dilakukan pada setiap blok sistem untuk memastikan fungsionalitas dan mengukur hasil tegangan keluaran pada sisi penerima. Hasil pengujian menunjukkan bahwa sistem mampu mentransmisikan energi listrik secara nirkabel dengan tegangan output tertinggi sebesar 8,53 V, dan konfigurasi lainnya menghasilkan tegangan 5,12 V, sesuai target sistem. Seluruh proses telah melalui tahap pengukuran secara menyeluruh, baik dari sisi pembangkit, driver, hingga penerima. Dengan demikian, alat yang dirancang telah berhasil menyelesaikan permasalahan awal terkait kebutuhan pengisian daya tanpa kabel dan bekerja sesuai tujuan penelitian.
