摘要：Summary These days, electric vehicle (EV) is using fuel cell as a prime source of energy because of its high promising performance and clean source of energy. However, due to low dynamic performance it alone cannot meet the fast changing load requirement during acceleration or sudden uphill, deceleration or sudden downhill. Therefore, in EV, main source is used in appropriate combination with auxiliary source. This article presents a comprehensive state-of-the-art of control strategies for maintaining constant DC bus voltage under transient load condition. It also presents a complete modeling by including boost converter modeling with main source and buck boost converter modeling with auxiliary source. Further, the dynamic evolution controller and Lyapunov-based control strategies for EV has been discussed with drive cycle.
