Abstract: A charging and discharging device includes: step-up/step-down converter including reference terminals, a first and second input/output terminals; and a power storage element connected between one of the reference terminals and the second input/output terminal, wherein the step-up/step-down converter is a polarity inversion type bidirectional DC-DC converter which charges the power storage element by inverting a polarity of a first DC voltage input from the first input/output terminal using a potential of the reference terminal as a reference potential and stepping up/down the first DC voltage to output a second DC voltage from the second input/output terminal, and discharges the power storage element by inverting a polarity of a third DC voltage input from the second input/output terminal using a potential of the reference terminal as a reference potential and stepping up/down the third DC voltage to output a fourth DC voltage from the first input and input/output terminal.

Abstract: A plurality of conductive parts are aligned along a rotational direction of a rotor. A different-thickness part relatively differs in thickness in one direction. In the rotor, a plurality of gaps are provided to separate the plurality of conductive parts from each other. An excitation coil is annularly arranged on a counter surface of a substrate. A detection coil is disposed inside the excitation coil on the counter surface of the substrate. A detection electrode part is disposed on the counter surface of the substrate such that the detection electrode part overlaps part of a rotation trajectory of the different-thickness part at a time of rotation of the rotor in plan view in the one direction, and the detection electrode part is configured to detect capacitance generated between the detection electrode part and the rotor.
