Abstract: A power supply device includes a power transmission coil which supplies electric power from outside the body in a non-contact manner via a power reception coil of an intracorporeal implanting-type medical appliance to which a drug solution is injected from outside the body. A support supports the power transmission coil, and an adhesive part is formed on the side of the support facing the body surface of a living subject.

Abstract: A power conversion device converting and outputting a characteristic of input power, includes: a power conversion unit including a normally-on type first switching element made of a nitride-based semiconductor material and converting the characteristic of power by a switching operation performed by the first switching element; an operation control unit controlling a switching operation of the first switching element; and an intelligent power switch including: a second switching element provided on a power input side of the power conversion unit and turning on/off power input to the power conversion unit; and a protection control unit including a current detection unit detecting a current flowing in the second switching element and controlling on/off of the second switching element and turn off the second switching element in a case where a current detected by the current detection unit exceeds a threshold value.
