PROBLEM TO BE SOLVED: To provide a power conversion system having necessary cooling performance even when a vehicle is stopped.SOLUTION: A power conversion system is such as to convert electric power from a power supply line to electric power to be supplied to load of an electric vehicle. A first conversion part supplies electric power to a subsidiary part including at least air conditioning or lighting of the electric vehicle. A second conversion part supplies electric power to a driving part of the electric vehicle. A first radiation fin is mounted on the first conversion part and extends to the outside part of the power conversion system. A second radiation fin is mounted on the second conversion part and extends to the outside part of the power conversion system. An air blower blows air to the first radiation fin during the vehicle is stopped.SELECTED DRAWING: Figure 3
【課題】車両の停車中であっても、必要な冷却性能を有する電力変換装置を提供する。【解決手段】本実施形態による電力変換装置は、電源線からの電力を、電気車の負荷に供給する電力へ変換する電力変換装置である。第1変換部は、電気車の少なくとも空調または照明を含む補助部に電力を供給する。第2変換部は、電気車の駆動部に電力を供給する。第1放熱フィンは、第1変換部に設けられ、電力変換装置の外部へ延伸する。第2放熱フィンは、第2変換部に設けられ、電力変換装置の外部へ延伸する。送風機は、車両の停車中において第1放熱フィンに送風する。【選択図】図3
