Abstract

Wireless Power Transfer (WPT) merupakan salah satu metode charging kendaraan listrik yang kini tengah mengalami perkembangan. Mentransfer daya secara nirkabel dapat mengurangi resiko pengguna tersengat listrik dan juga rugi-rugi yang terjadi dalam charging menggunakan kabel. Akan tetapi, daya output WPT cenderung berubah-ubah bergantung dengan jarak dan frekuensi. Diperlukan sebuah DC-DC converter yang dapat menstabilkan daya yang ditransfer dari WPT ke baterai. Zeta converter dipilih karena memiliki efisiensi yang tinggi dan juga menghasilkan ripple arus dan tegangan yang rendah sehingga dapat memaksilkan daya yang akan diterima oleh baterai lithium-polymer. Pada Implementasinya, zeta converter memiliki efisiensi rata-rata 73.7% pada pembebanan 20% sampai 100%. Metode Constant Current – Constant Voltage memiliki reliabilitas tinggi dalam menjaga tegangan dan arus charging secara konstan dan dapat menghasilkan arus konstan 2 Ampere dan tegangan konstan 14.4 Volt. Pada pengujian charging baterai Li-Po, didapatkan bahwa keseluruhan proses charging membutuhkan waktu selama 56 menit dengan rincian 19 menit pada mode Constant Current dan 37 menit pada mode Constant Voltage. Pada pengujian WPT zeta converter baterai Li-Po didapatkan bahwa keseluruhan proses charging membutuhkan waktu selama 52 menit dengan rincian 19 menit pada mode Constant Current dan 33 menit pada mode Constant Voltage.

Wireless Power Transfer (WPT) is a method of charging electric vehicles that is currently experiencing development. Transferring power wirelessly can reduce the user's risk of electric shock and also the losses that occur when charging using a cable. However, WPT output power tends to vary depending on distance and frequency. A DC-DC converter is needed that can stabilize the power transferred from the WPT to the battery. The Zeta converter was chosen because it has high efficiency and also produces low current and voltage ripples so that it can maximize the power received by the lithium-polymer battery. In its implementation, the zeta converter has an average efficiency of 73.7% at a load of 20% to 100%. The Constant Current - Constant Voltage method has high reliability in maintaining constant charging voltage and current and can produce a constant current of 2 Amps and a constant voltage of 14.4 Volts. In the Li-Po battery charging test, it was found that the entire charging process took 56 minutes, with details of 19 minutes in Constant Current mode and 37 minutes in Constant Voltage mode. In testing the WPT zeta converter for Li-Po batteries, it was found that the entire charging process took 52 minutes, with details of 19 minutes in Constant Current mode and 33 minutes in Constant Voltage mode
