Abstract
Transisi energi menuju energi baru terbarukan (EBT) menjadi tidak terhindarkan seiring dengan perkembangan teknologi yang pesat. Salah satunya adalah perkembangan teknologi kendaraan listrik dengan konsep Vehicle-to-Grid (V2G) yang memungkinkan kendaraan dapat melakukan transfer daya kembali ke grid saat diperlukan. Untuk itu, diperlukan konverter DC-AC Bidirectional yang mampu mengalirkan daya secara dua arah, yaitu dengan mode operasi rectifier maupun mode inverter. Topologi yang digunakan adalah Single Phase Full-Bridge Current-Controlled Voltage Source Inverter (CC-VSI) dengan metode Kontrol Arus Histerisis dan pengaturan tegangan berbasis Logika Fuzzy. Penelitian ini bertujuan menganalisis karakteristik mode-mode operasinya serta menganalisis respon sistemnya. Didapatkan hasilnya untuk menjaga tegangan bus DC pada nilai nominal, diperlukan kombinasi pembebanan/ injeksi arus terhadap arus referensinya yang sesuai. Rentang frekuensi sinyal histerisis didapatkan nilai yang sesuai terhadap desain dan simulasi pada rentang frekuensi 7,3-15,15 kHz. Mode rectifier ditandai dengan adanya beda fasa antara arus AC terhadap tegangannya dengan efisiensi rata-ratanya 90,3 %. Sedangkan, mode inverter memiliki nilai antar keduanya yang sefasa dengan efisiensi 87,8 %. Pengaturan tegangan logika fuzzy memungkinkan stabilitas bus DC terjaga dengan adanya perubahan beban/ injeksi arus secara dinamis dengan respon sistem yang cukup cepat pada settling time berkisar 1-4 detik, meski terdapat steady state error di kisaran 5-10 %.

The energy transition to new renewable energy (RNE) is becoming inevitable with rapid technological development. One is the development of electric vehicle technology with the Vehicle-to-Grid (V2G) concept that allows vehicles to transfer power back to the grid when needed. For this, a DC-AC bidirectional converter is required that is capable of flowing power in two directions, in both rectifier and inverter operating modes. The topology used is a Single Phase Full-Bridge Current-Controlled Voltage Source Inverter (CC-VSI) with hysterical current control method and Fuzzy Logic-based voltage regulation. The study aims to analyze the characteristics of the operating mode as well as the response of the system. To obtain the result to keep the voltage of the DC bus at the nominal value, a combination of load/ current injection against the corresponding reference current is required. The hysterical signal frequency range is obtained to match the design and simulation in the frequencies of 7.3-15.15 kHz. The rectifier mode is characterized by the phase difference between the AC current and its voltage with an average efficiency of 90.3%. Instead, the inverter mode has the values between the two at an efficiencies of 87.8%. The fuzzy logic voltage regulation allows the stability of the DC bus awake in the presence of dynamic change of load/ injection of current with a sufficiently fast system response at settling times ranging from 1-4 seconds, even though there are steady state errors in the range of 5-10%.
