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.
