Summary:To provide a power supply unit or the like capable of improving convenience.SOLUTION: A power supply unit in one embodiment comprises: a power supply part for supplying power to an electric medical device; a first impedance control part arranged on a path except for an input path of an electric signal obtained in the electric medical device to another device, out of power circulation paths between the power supply part and the electric medical device; and a second impedance control part arranged on the input path out of paths between the power supply part and the other device. According to a supply state of power to the electric medical device, an impedance state on each of the first and second impedance control part and the second impedance control part is shifted.SELECTED DRAWING: Figure 1 【課題】利便性を向上させることが可能な電源装置等を提供する。【解決手段】本開示の一実施の形態に係る電源装置は、電気医療デバイスに対して電力を供給する電源部と、電源部と電気医療デバイスとの間における電力の循環経路のうちの、電気医療デバイスにて得られた電気信号の他の装置への入力経路を除く経路上に配置された第１のインピーダンス制御部と、電源部と上記他の装置との間の経路のうちの上記入力経路上に配置された第２のインピーダンス制御部と、を備えている。電気医療デバイスへの電力の供給状況に応じて、第１および第２のインピーダンス制御部におけるインピーダンス状態がそれぞれ、遷移するように構成されている。【選択図】図１
