| description | PROBLEM TO BE SOLVED: To provide a technology capable of improving the efficiency of a vehicle power supply system having a plurality of DC-DC converters.SOLUTION: A vehicle power supply system 2 according to one embodiment comprises a plurality of parallel-connected DC-DC converters 28 and 30. The vehicle power supply system 2 comprises: a cooling flow channel PF in which cooling medium for cooling down the plurality of DC-DC converters 28 and 30 flows; and temperature acquisition means St that acquires a temperature of the cooling medium. The vehicle power supply system 2 further comprises: loss identification means 60 that identifies a loss power for each number of driven DC-DC converters 28 and 30 by using output currents of the plurality of the DC-DC converters 28 and 30, output voltages of the plurality of the DC-DC converters 28 and 30, and the acquired temperature; and the-number-of-converters selection means 60 that selects the number of driven DC-DC converters that brings about the minimum loss power of the identified loss powers.SELECTED DRAWING: Figure 1
【課題】 複数のＤＣ−ＤＣコンバータを有する車両用電源システムの効率化を実現することができる技術を提供する。【解決手段】本明細書が開示する車両用電源システム２の一形態は、並列に接続された複数のＤＣ−ＤＣコンバータ２８，３０を有する。車両用電源システム２は、複数のＤＣ−ＤＣコンバータ２８，３０を冷却する冷却媒体が流れる冷却流路ＰＦと、冷却媒体の温度を取得する温度取得手段Ｓｔと、を備える。車両用電源システム２は、さらに、複数の前記ＤＣ−ＤＣコンバータ２８，３０の出力電流と、複数の前記ＤＣ−ＤＣコンバータ２８，３０の出力電圧と、取得された前記温度と、を用いて、ＤＣ−ＤＣコンバータ２８，３０の駆動台数ごとの損失電力を特定する損失特定手段６０を備え、特定された損失電力のうち、最も小さい損失電力となるＤＣ−ＤＣコンバータの駆動台数を選択する台数選択手段６０を備える。【選択図】図１ |
