Abstract

Pemanasan global, yang disebabkan oleh peningkatan emisi karbon dari kendaraan bermotor, menjadi salah satu tantangan utama dalam perubahan iklim. Sektor transportasi di Indonesia, yang sangat bergantung pada energi fosil, merupakan salah satu kontributor utamanya. Sebagai solusi, Fuel Cell Electric Vehicle (FCEV) yang menggabungkan fuel cell sebagai sumber energi utama dan baterai sebagai penyimpan sekunder menawarkan alternatif ramah lingkungan. Untuk mengoptimalkan sistem hibrida ini, penelitian ini merancang dan mengimplementasikan sebuah konverter DC-DC bidirectional SEPIC-ZETA yang diatur menggunakan metode Kontrol Arus Histerisis (HCC). Hasil pengujian pada prototipe membuktikan bahwa konverter berhasil bekerja secara dua arah: mode SEPIC (discharge) dengan efisiensi rata-rata 72.9% dan mode ZETA (charge) dengan efisiensi rata-rata 70.27%. Metode HCC yang diterapkan menunjukkan respon dinamis yang sangat cepat, dengan waktu transisi pergantian mode hanya 1.651 ms, yang esensial untuk aplikasi FCEV. Meskipun demikian, ditemukan adanya tantangan stabilitas berupa lonjakan tegangan saat transien yang menjadi catatan untuk pengembangan di masa depan. Penelitian ini berhasil memvalidasi kelayakan topologi SEPIC-ZETA sebagai solusi manajemen daya yang responsif untuk sistem FCEV.

Global warming, driven by increased carbon emissions from motor vehicles, poses a major challenge to climate change. The transportation sector, which is heavily reliant on fossil fuels, is one of the largest contributors to carbon emissions in Indonesia. As a solution, the Fuel Cell Electric Vehicle (FCEV), which combines a fuel cell as the primary energy source and a battery for secondary storage, offers an environmentally friendly alternative. To optimize this hybrid system, this research designs and implements a bidirectional SEPIC-ZETA DC-DC converter regulated using the Hysteresis Current Control (HCC) method. Hardware prototype testing has verified that the converter successfully operates bidirectionally. The SEPIC (discharge) mode achieved an average efficiency of 72.9%, while the ZETA (charge) mode reached an average efficiency of 70.27%. The implemented HCC method demonstrated a highly dynamic response, with a mode transition time of only 1.651 ms, which is essential for FCEV applications. Nevertheless, a stability challenge in the form of a significant voltage overshoot during transients was identified, providing a key area for future development. This research successfully validates the viability of the SEPIC-ZETA topology as a responsive power management solution for FCEV systems.
