Abstract: A drive device that drives a semiconductor switching device includes a capacitor, an output selection unit that selects whether or not to supply a charge of the capacitor to a conduction control terminal of the semiconductor switching device, and a charge consumption unit that supplies the charge of the capacitor to a portion other than the conduction control terminal, thereby consuming the charge of the capacitor.

Abstract: An electromagnetic resonance coupler according to one aspect of the present disclosure includes a first layer, a second layer which faces a first principal surface of the first layer, a third layer which faces a second principal surface of the first layer, a first resonator which is located between the first layer and the second layer, and a second resonator which is located between the first layer and the third layer. A dielectric constant of the first layer is lower than either one of a dielectric constant of the second layer and a dielectric constant of the third layer. A dielectric dissipation factor of the first layer is higher than either one of a dielectric dissipation factor of the second layer and a dielectric dissipation factor of the third layer.
