Abstract
Based on the study of the solid oxide fuel cell power generation system, and to release the energy of converter inductance and reduce the charging time of capacitance for the purpose, adding a flyback winding in DC / DC converter is proposed. Its output terminal and ground terminal are connected with the DC / DC converter output terminal and the output ground terminal separately, forming the output circuit and releasing excess energy when the input inductor starts, to ensure the stability of the output voltage of the DC/DC bus. Fuzzy PID control strategy is used in inverter output voltage control, by monitoring the system output voltage and the given voltage based on-line adjustKP,Kd,Ki control output, when solid oxide fuel cell output voltage is instable. Comparative results show that its performance is superior to the traditional PID control strategy. The simulation of the solid oxide fuel cell power generation system has verified the above theoretical analysis by using Matlab software to build the model system.关键词
