Pada penelitian ini, dipelajari sistem wireless power transfer menggunakan series-series inductive coupled magnetic resonance. Penelitian dilakukan dengan menggunakan dua buah coil melingkar yang diletakkan secara terpisah dan berhadap-hadapan sebagai coil transmitter dan coil receiver. Pengaruh dari perubahan jarak antar coil serta variasi beban pada efisiensi daya dan besaran-besaran listrik yang lain seperti arus, tegangan, serta beda fase diamati pada penelitian ini. Jumlah lilitan pada masing-masing coil, tegangan input pada sisi transmitter, sudut kemiringan atau arah hadap coil, serta frekuensi listrik sistem dijaga konstan. Hasil penelitian ini menunjukkan bahwa baik jarak antar coil maupun variasi nilai beban mempengaruhi keseluruhan unjuk kerja dari sistem wireless power transfer ini. Hasil yang didapat juga sesuai dengan prediksi teoritis.

The wireless power transfer system using series-series inductive coupled magnetic resonance is studied in this work. The research is conducted using two separated circular coil facing each other serving as transmitter and receiver coil respectively. The effect of distance variation between two coils as well as loading variation to power efficiency and other electrical properties such as current, voltage, and phase different are observed. The coil's number of turn, transmitter input voltage, coil's attitude, and electrical frequency of the system are kept constant. The results show that both the inter-coil distance and the load value affect the overall performance of wireless power transfer system and match the theoretical prediction.
