A power module includes a power circuit which includes one or more power semiconductors; and a control circuit which supplies a gate signal to each of the one or more power semiconductors. The control circuit includes one or more gate drivers which generate the gate signal in accordance with a control signal and in which a side to which the control signal is input and a side on which the gate signal is generated are insulated, a control input circuit to which the control signal is input and which supplies the control signal to the one or more gate drivers, and a control output circuit which supplies the gate signal to each of the power semiconductors.

Power module

A primary-side electrode and a secondary-side electrode of a power device are disposed so as to straddle plural separate primary and secondary wires in a first conductive layer, a second conductive layer includes plural separate primary and secondary wires, an insulating part is disposed in a first insulating layer in a region between the primary and secondary wires and directly below the power device, an intralayer insulating part is disposed in the second conductive layer in a region between the primary and secondary wires and directly below the power device, and a via that connects the primary wire in the first conductive layer and the primary wire in the second conductive layer and connects the secondary wire in the first conductive layer and the secondary wire in the second conductive layer is disposed in the first insulating layer directly below the primary-side and secondary-side electrodes of the power device.
