Abstract

Seiring dengan meningkatnya perhatian terhadap keberlanjutan di tingkat global, kendaraan listrik (Electric Vehicle atau EV) menjadi solusi utama dalam mengurangi emisi dan ketergantungan bahan bakar fosil. Namun, adopsi kendaraan listrik masih menghadapi berbagai tantangan, termasuk keterbatasan teknologi pengisian daya seperti durasi pengisian yang lama, efisiensi transfer daya yang belum optimal, serta jarak transfer daya yang terbatas pada sistem nirkabel. Teknologi Wireless Power Transfer (WPT) muncul sebagai solusi inovatif untuk menjawab tantangan tersebut, dengan potensi untuk memberikan pengisian daya tanpa kontak fisik, fleksibel, dan lebih nyaman dibandingkan metode konvensional. Penelitian ini bertujuan untuk melakukan studi komparatif topologi Double-Sided LCL dengan Seri-Seri pada sistem Wireless Power Transfer. Penelitian ini mencakup desain, simulasi, serta pembuatan prototipe menggunakan perangkat lunak PSIM dan Ansys Maxwell. Desain sistem yang direalisasikan memiliki daya 200 Watt pada tegangan input 48V yang bekerja pada frekuensi 85 kHz. Pada simulasi diperuntukkan sebagai pembuktian teori yang digunakan sebagai acuan. Diperoleh efisiensi 100% pada tahap simulasi saat jarak kumparan direpresentasikan berubah dari 1 hingga 10 cm. Pada realisasinya, diperoleh hasil implementasi dengan daya output maksimum yang diterima beban pada topologi seri-seri senilai 138,1 watt dengan efisiensi 65,2%. Sedangkan, pada topologi double-sided LCL daya output maksimum yang diterima beban senilai 103,5 watt dengan efisiensi 43,14%. Pengujian lainnya pada variasi beban dengan rentang 2 hingga 45 ohm menunjukkan perbedaan karakter dari kedua topologi. Diperoleh nilai daya output pada topologi seri-seri yang cenderung linear dengan kenaikan beban dengan perolehan daya 102,6 – 226,3 watt berurutan dari 10 – 45 ohm. Sedangkan, pada topologi double-sided LCL daya output cenderung konstan pada perubahan beban dengan rentang perolehan daya output senilai 102,3 – 122,5 watt pada beban 10 – 45 ohm. Perbedaan nilai pada simulasi dengan implementasi disebabkan oleh adanya rugi-rugi pada komponen inverter dan penyearah, resistansi parasitik pada kumparan, serta ketidaksempurnaan kopling magnetik. Meskipun demikian, penelitian ini berhasil mengimplementasikan sistem WPT dan menunjukkan bahwa topologi seri-seri menghasilkan daya yang lebih tinggi dibandingkan topologi double-sided LCL. Namun, topologi double-sided LCL mampu menghasilkan transfer daya yang lebih stabil terhadap perubahan jarak dan beban sistem.

As global attention to sustainability continues to increase, Electric Vehicles (EVs) have emerged as a key solution to reduce emissions and dependence on fossil fuels. However, the adoption of electric vehicles still faces several challenges, particularly in charging technology, such as long charging times, suboptimal power transfer efficiency, and limited transfer distance in wireless charging systems. Wireless Power Transfer (WPT) technology has emerged as an innovative solution to address these challenges, offering contactless, flexible, and more convenient charging compared to conventional methods. This research aims to conduct a comparative study between the Double-Sided LCL and Series–Series topologies in a Wireless Power Transfer system. The study includes system design, simulation, and prototype implementation using PSIM and Ansys Maxwell software. The realized system is designed for a rated power of 200 W with a 48 V input voltage operating at a frequency of 85 kHz. Simulations are conducted to validate the theoretical analysis and serve as a reference for implementation. Simulation results show an efficiency of 100% when the coil distance is varied from 1 to 10 cm. In practical implementation, the maximum output power delivered to the load for the Series–Series topology is 138.1 W with an efficiency of 65.2%. Meanwhile, the Double-Sided LCL topology achieves a maximum output power of 103.5 W with an efficiency of 43.14%. Additional tests under load variations ranging from 2 to 45 ohms reveal distinct characteristics between the two topologies. The Series–Series topology exhibits an output power that increases linearly with load, achieving power levels of 102.6–226.3 W for loads ranging from 10 to 45 ohms. In contrast, the Double-Sided LCL topology demonstrates a relatively constant output power under load variations, with output power ranging from 102.3 to 122.5 W for loads between 10 and 45 ohms.The discrepancies between simulation and experimental results are attributed to losses in the inverter and rectifier components, parasitic resistance in the coils, and imperfect magnetic coupling. Nevertheless, this research successfully implements a WPT system and demonstrates that the Series–Series topology delivers higher output power compared to the Double-Sided LCL topology. However, the Double-Sided LCL topology provides more stable power transfer performance against variations in coil distance and load conditions.
