基于TC275的质子交换膜燃料电池控制器设计OA北大核心CSTPCD

In order to enhance the energy conversion efficiency of the proton exchange membrane fuel cell(PEMFC)system and reduce design costs,a fuel cell intelligent controller based on Infineon's TC275 microprocessor is designed by analyzing the functional requirements of the fuel cell control system.The controller is used to collect parameters such as temperature,humidity,pressure,and flow of the supplied fuel and the temperature,pressure,output voltage,and current during operation of fuel cell stack.According to the load power demand,the real-time calculation of parameters are conducted by means of the intelligent algorithm,the corresponding control instructions are output to adjust the flowmeter and other executive devices,so as to maintain the intelligent,efficient,safe and stable operation of the fuel cell system.In the controller,RS 485 communication is used to realize the information exchange between the fuel cell system and the host computer,and control the operating conditions of the fuel cell system in real time.The controller is applied to the 3 kW PEMFC system,which has excellent monitoring performance,and stable and reliable operation.In comparison with the established simulation model,the experimental results are consistent and meet the control requirements of the fuel cell system.
