Abstract
ObjectProvided is a power supply device and the like capable of improving convenience.Solving meansA power supply device according to an embodiment of the present disclosure include a power supply unit that supplies power to an electromedical device, a first impedance control unit disposed on a path of a circulation path of the power between the power supply unit and the electromedical device, excluding an input path for inputting an electrical signal obtained in the electromedical device to another device, and a second impedance control unit disposed on the input path of a path between the power supply unit and the other device. An impedance state of each of the first and second impedance control units transitions in accordance with a supply state of the power to the electromedical device.
