PROBLEM TO BE SOLVED: To provide a transformation device that allows preventing a reduction in the maximum power storage amount in which a first capacitor can store, without an increase in load in operation and without providing a discharge circuit.SOLUTION: A DC/DC converter 12 functioning as a transformation device transforms an output voltage from a first capacitor 11 into a target voltage and applies the transformed voltage to a second capacitor 14. A control unit 22 obtains temperature information indicating the temperature of the first capacitor 11 from a temperature detection unit 16. The control unit 22 increases the target voltage when determining that the temperature of the first capacitor 11 indicated by the obtained temperature information is equal to or more than a reference temperature.

    【課題】作動中の負荷を増やさず、更には、放電回路を設けることなく、第1蓄電器が蓄えることが可能な最大蓄電量の低下を抑制することができる変圧装置の提供。【解決手段】変圧装置として機能するDC/DCコンバータ12は第1蓄電器11の出力電圧を目標電圧に変圧し、変圧した電圧を第2蓄電器14に印加する。制御部22は、温度検出部16から第1蓄電器11の温度を示す温度情報を取得する。制御部22は、取得した温度情報が示す第1蓄電器11の温度が基準温度以上であると判定した場合に、目標電圧を上昇させる。【選択図】図1
