Analysis. Design and Implementation of Fuel Cell LLC Resonant Converter Used in Electrical Vehicle

摘要

This paper presents actually analysis and design of a full bridge LLC resonant converter appropriate to a fuel cell used in electrical vehicle. In fact, the LLC converter has various required aspects such as high efficiency, low electromagnetic interference (EMI) and high power density. It provides additionally a detailed practical design aspect of a full bridge LLC resonant converter. Therefore, the resonant converter is made by a bridge on the primary side and a bridge rectifier on the secondary side. It includes the determination of the selection of components such as resonant inductor, resonant capacitor and magnetization inductor. Furthermore, the performance parameters such as voltage gain and output voltage ripple are determined. An experimental converter prototype has been simultaneously designed, built up, and tested in the laboratory. Finally, a 30V -input and 180V - output 300W prototype is built to demonstrate of the proposed converter and analysis.
