Embedded energy management based on DC/DC converters - Ultracapacitors and Fuel Cell
Résumé
This paper presents the Ultracapacitors (UC) and Fuel Cell coupling with an original energy management method for Hybrid Electric Vehicles (HEVs) applications. Ultracapacitors are coupled to the DC-link through Buck-Boost converters. The Fuel Cell is connected to the DC-link using boost converter. An asynchronous machine is used like traction motor; it is coupled to DC-link using an inverter. The main contribution of this paper is focused on Hybrid Sources (Ultracapacitors and Fuel Cell) currents, DC-link voltage control, and Asynchronous machine Speed control based on polynomial controllers called RST correctors. Through some simulations and experimental results, the authors present an improved energy management for Hybrid Electric Vehicles applications.
