SOFC 연료전지용 인버터 시스템의 특성 및 필터에 관한 연구

초록

Recently, a fuel cell stack having advantages of reducing or increasing the number of stack cells of the fuel cell, reducing the cost of the product, facilitating the fabrication, reducing the failure rate, and extending the life of the stack by increasing the output voltage is generally in progress. Particularly, a solid oxide fuel cell (SOFC) fuel cell has advantages of increasing the number of stack cells to increase the voltage per cell (low current output), lowering the manufacturing cost of the inverter, and increasing the number of stack cells, The fuel cell stack has been actively studied. As the number of stacked solid oxide fuel cell (SOFC) cells increases with the input of the inverter in the direction corresponding to the increase of the voltage per cell, the high efficiency and low efficiency inverter with high voltage and low current are being actively studied. In this paper, we analyze the research direction and the optimum circuit topology of the inverter which is the essential equipment to convert the fuel cell output to the domestic power source, and make prototype, performance test, We test the performance and verify the performance of filter design, filter prototype manufacturing, electromagnetic wave test and filter considering newly added electromagnetic field test.
