Provided is a rotating connector device with which it is possible to suppress an increase in the size of the device, and to reliably suppress a decrease in electromagnetic compatibility due to electromagnetic noise and to stabilize characteristic impedance. A rotating connector deviceis provided with a fixed-side housing, a rotating-side housingwhich is free to rotate relative to the fixed-side housing, and a plurality of flat cableswhich are formed by covering conductors with an insulating material and which are accommodated in a stacked state in an annular accommodating space S formed between the fixed-side housingand the rotating-side housing, wherein a shield filmis disposed at least between a first flat cableincluding first and second communication circuit conductorsand a second flat cableadjacent to the first flat cable, among the plurality of flat cables

Rotating connector device

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.
