연료전지 하이브리드 시스템을 위한 제어기법

This paper describes a power control scheme for a fuel cell hybrid system. The fuel cell hybrid system consists of a fuel cell system , battery as an auxiliary power source and power converters, where the fuel cell system supplies the power required by a load and charges the battery. In the proposed power control strategy, the power balance between fuel cell and battery is managed properly based on the battery SOC and the power demand to improve the efficiency of fuel cell hybrid system. A dual boost converter with a dead-beat control is hired to control the output power of the fuel cell stack and manage its operation region for improving the performance of fuel cell system.
