Abstract
Penelitian ini merancang, mengimplementasikan, dan menganalisis kinerja inverter Sinusoidal Pulse Width Modulation (SPWM) pada sistem Wireless Power Transfer (WPT) untuk aplikasi kendaraan listrik. Latar belakang penelitian ini adalah kebutuhan akan alternatif pengisian daya yang lebih aman dan nyaman dibandingkan metode pengisian daya dengan kabel, seiring dengan target net zero emission (NZE) pada tahun 2060. Metodologi penelitian mencakup perancangan sistem WPT dengan target daya 150 watt pada frekuensi resonansi 20 kHz, pemodelan dan simulasi menggunakan software PSIM dan Ansys Maxwell 3D untuk menganalisis parameter kumparan seperti induktansi dan koefisien kopling, serta pembuatan prototipe fisik. Hasil pengujian menunjukkan bahwa daya output maksimum yang dicapai adalah 47,08 watt menggunakan inverter Square Wave dan 17,1 watt menggunakan inverter SPWM, keduanya pada jarak optimal 5 cm. Perbedaan antara hasil simulasi ideal dan realisasi prototipe disebabkan oleh adanya rugi-rugi pada komponen inverter dan penyearah, resistansi parasitik pada kumparan, serta ketidaksempurnaan kopling magnetik. Kesimpulannya, meskipun target daya 150 watt belum tercapai, penelitian ini berhasil mengimplementasikan sistem WPT dan menunjukkan bahwa inverter Square Wave menghasilkan efisiensi lebih tinggi dibandingkan SPWM dalam konfigurasi ini akibat switching loss yang lebih rendah. Disarankan untuk penelitian selanjutnya agar menggunakan material dan komponen dengan rugi-rugi yang lebih rendah untuk meningkatkan efisiensi sistem.

This research designs, implements, and analyzes the performance of a Sinusoidal Pulse Width Modulation (SPWM) inverter in a Wireless Power Transfer (WPT) system for electric vehicle applications. The background for this study is the need for a safer and more convenient charging alternative compared to wired charging methods, in line with the net-zero emission (NZE) target for 2060. The research methodology includes designing a WPT system with a 150-watt power target at a 20 kHz resonant frequency, modeling and simulation using PSIM and Ansys Maxwell 3D software to analyze coil parameters such as inductance and coupling coefficient, and fabricating a physical prototype. The test results show that the maximum achieved output power was 47.08 watts using a Square Wave inverter and 17.1 watts using an SPWM inverter, both at an optimal distance of 5 cm. The discrepancy between the ideal simulation results and the prototype realization was caused by losses in the inverter and rectifier components, parasitic resistance in the coils, and imperfect magnetic coupling. In conclusion, although the 150-watt power target was not met, this research successfully implemented the WPT system and demonstrated that the Square Wave inverter yields higher efficiency than the SPWM inverter in this configuration due to lower switching losses. It is recommended for future research to use materials and components with lower losses to improve system efficiency.
