To provide a DC/DC converter and a power supply system that do not require excessive speeding up and large current.SOLUTION: A DC/DC converter is connected between a capacitor that is connected to a vehicle load and temporarily stores electric power and a secondary battery mounted on the vehicle, and bidirectionally converts the voltage. When the voltage of the capacitor is lower than a first voltage, the DC/DC converter converts the voltage of the secondary battery to charge the capacitor, and when the voltage of the capacitor is equal to or higher than the second voltage higher than the first voltage, and the DC/DC converter converts the voltage of the capacitor to charge the secondary battery.SELECTED DRAWING: Figure 1
【課題】過度な高速化及び大電流化が不要なDC/DCコンバータ及び電源システムを提供する。【解決手段】DC/DCコンバータは、車両の負荷に接続されて一時的に電力を蓄電する蓄電器と、車両に搭載された二次電池との間に接続されて双方向に電圧を変換する。DC/DCコンバータは、蓄電器の電圧が第1電圧より低い場合、二次電池の電圧を変換して蓄電器を充電し、蓄電器の電圧が前記第1電圧より高い第2電圧以上である場合、蓄電器の電圧を変換して二次電池を充電する。【選択図】図1
