Design a Power Converter to Charge a Hybrid Electric Vehicle

In Hybrid Electric Vehicle (HEV) applications, renewable energy sources like solar PV system and fuel-cell are highly suggested. Furthermore, the HEV storage system alongside with the DC-DC controller part, play a significant role in the evolution of electric vehicles. To charge the HEV's batteries, this study offers a new DC-DC converter topology that combines a solar PV system and fuel cells as two inputs. These pollution-free sources create electric energy, which is stored in batteries and utilized for propulsion. In addition, the proposed topology and operation modes are discussed. According to the results, the suggested system can charge the batteries with very low output current and voltage ripple.
