초록
In this paper, we demonstrated the efficiency of the LLC resonant converter to build high-efficiency conversion, miniaturization, light weight, reliability and stability required by various power converters in auxiliary power supplies of railway vehicles. As a result, the LLC resonant converter has lower power loss than the flyback converter even though one MOSFET was added. The LLC converter is judged as a power conversion device that can be utilized in terms of manufacturing operation and price rationality because it can significantly reduce the volume and size of the transformer in the SIV system.
