Abstract:

The power conditioning system of a fuel cell power plant is very important to the reliability and efficiencyof the power plant system as well as to the quality of the output waveform. In this paper , the optimizedcooperation between the main circuit structure of the power conditioner and the fuel cell parameters is investigatedby simulation and experiment , and the law of designing efficient main circuit for the power conditioning systemis proposed. By investigating the mathematical model of the inverter system , some guidance is provided forthe inverter output waveform control. A digital intelligent control system with good practicability , high performanceand low cost is then designed , in which the output waveform control is emphasized. Moreover , the waveformcontrol scheme based on the sliding-mode control policy is investigated , and is then testified by experiments.It is found that the proposed system satisfies the requirements of the power plant , and possesses good reliability, high output waveform quality and great efficiency.

Key words: fuel cell power plallt, power conditioning system, inverter, waveform control, sliding-mode control
