Abstract: A control board for a power conversion device, the control board including a board body that is a multilayer board; a first circuit mounted on a first surface of the board body and including a heat generator; a second circuit mounted on the first surface of the board body, the second circuit using a voltage different from a voltage of the first circuit; an insulation region formed on the first surface of the board body, the insulation region performing insulation between the first circuit and the second circuit; and a pattern of a thermal conductive material formed on an internal layer of the board body, extending in a region overlapping with the insulation region as seen from a direction orthogonal to the first surface of the board body, and thermally connected to the heat generator.

Abstract: An inverter device that includes an inverter circuit that converts power between DC power and multi-phase AC power; a drive circuit that transfers a drive signal to each of a plurality of switching elements that form the inverter circuit to cause a switching element of the plurality of switching elements to perform turn-on, in which the switching element is caused to transition from an off state to an on state, and turn-off, in which the switching element is caused to transition from the on state to the off state; and a current detection circuit that detects a current that flows through each of the plurality of switching elements.
