Abstract

Motor induksi tiga fasa dapat berperan sebagai genarator induksi saat melakukan pengereman regeneratif. Artinya motor induksi tiga fasa tersebut berubah fungsi menjadi penyuplai daya. Pengereman regeneratif dapat dimanfaatkan dengan menyimpan daya dari motor induksi tiga fasa ke media penyimpanan sehingga dapat menekan konsumsi listrik pada kendaraan listrik. Konverter bidirectional adalah rangkaian yang mampu memanfaatkan pengereman regeneratif. Dalam tugas akhir ini, dilakukan manajemen energi pada kendaraan listrik menggunakan konverter AC-DC-DC isolated dengan konsep bidirectional. Sumber tegangan berasal dari baterai 96 V 100 Ah dinaikkan dua kali menggunakan High Frequency Transformer (HFT) dan menjadi 192 V. Tegangan 192 V dari HFT ditingkatkan level tegangannya menjadi 590 V dan masuk ke inverter tiga fasa berbasis Field Oriented Control (FOC). Penggerak utama menggunakkan motor induksi tiga fasa dengan rating daya 10 HP. Hasil simulasi menunjukkan bahwa konverter AC-DC-DC isolated mampu beroperasi bidirectional baik saat motor akselerasi maupun pengereman regeneratif. Untuk uji regeneratif dengan variasi kecepatan, Daya balik yang tersimpan ke baterai mencapai 98.12%. Sedangkan untuk uji regeneratif dengan variasi torsi, daya balik yang tersimpan ke baterai mencapai 99%. ====================================================================================================== A three phase induction motor can serve as induction generator when on regenerative braking condition. It means that three phase induction motor change the mode to a supplier of power. The adventages of regenerative braking can be used to store power from a three phase induction motor to the storages so the electric consumption of electric vehicles can be reduced. A bidirectional converter capable of get that advantages from regenerative braking. In this final project, conducted the management energy on electric vehicles using AC-DC-DC isolated converter with bidirectional concept. The source using battery 96 V 100 Ah get raised twice using High Frequency Transformator (HFT) and become 192 V. The 192 V of votages from HFT are improved that voltage level until 590 V and enter to three phase inverter based on Field Oriented Controlled (FOC). The motor drive using three phase induction motor with power rated 10 HP. Simulation results shows that AC-DC-DC isolated converter capable of operating bidirectional either while motor acceleration and regenerative braking. Regenerative test of speed variations show that 98.12% reverse power could charged into battery. For regenerative test of load-torque variations show that 99% reverse power could charged into battery.
