An Improved Control of High Efficiency Series Converter for Fuel Cell/Supercapacitor Hybrid System
摘要
This paper presents improved control law of a hybrid system using a series converter connected between fuel cell and supercapacitor. The presented topology provides proper utilization of SC and achieves high efficiency in a steady state. In normal operating mode, the reference voltage of the supercapacitor is defined by the proposed controller so that the voltage accross series converter reaches zero in a steady-state. Simulation and experimental results for a given load profile are presented in this paper to validate the proposed improved control law.
