| چکیده مقاله |
| DC-DC converters are usually utilized for fuel cell power system interface to regulate the output voltage according to the load characteristics. In some applications, the converters are needed to be installed in parallel structure to increase the power system reliability and in some cases, adapt the system electric power level. In this paper, a test setup is designed and implemented to utilize two parallel DC-DC power converters with asynchronous control systems. The test setup is developed to be used for a PEM fuel cell power system and the converters' operating points are selected considering the fuel cell voltage-current curve. The fuel cell operating point is simulated by a lead-acid battery pack as the input source. To simulate a hybrid power system, another battery pack is connected to the converters output. The converters input source and output battery pack are hybridized to supply the load. The experimental results confirmed the acceptable current sharing between the two converters by the implemented setup despite their asynchronous control systems. |
