To perform buck-boost operation with simple control.SOLUTION: A lifting and lowering pressure device according to an embodiment includes a plurality of capacitors and a plurality of switches. The plurality of capacitors are provided between a first battery and a second battery having a rated voltage lower than that of the first battery, one end of which is connected to the first battery, and each of which is connected to the second battery in parallel. The plurality of switches are respectively provided in the plurality of capacitors to switch the connection state with the adjacent capacitors.SELECTED DRAWING: Figure 1 【課題】昇降圧動作を簡便な制御で行うこと。【解決手段】実施形態に係る昇降圧装置は、複数のキャパシタと、複数のスイッチとを備える。複数のキャパシタは、第１バッテリと第１バッテリよりも定格電圧が低い第２バッテリとの間に設けられ、一端が第１バッテリに接続し、それぞれが並列して第２バッテリに接続する。複数のスイッチは、複数のキャパシタそれぞれに設けられ、隣接するキャパシタとの接続状態を切り替える。【選択図】図１
