Abstract: A mounting pedestal on which a heat generating component is disposed is provided. The mounting pedestal includes a substrate which includes a plurality of bending portions at which the substrate is bent in a staircase shape. An insulating layer is disposed on a surface of the substrate. An interconnecting line is disposed on the insulating layer. In the mounting pedestal, the interconnecting line extends across the plurality of bending portions. In each of the plurality of bending portions, a corner radius (R) of a mountain portion is greater than a corner R of a valley portion.

Abstract: A power converter includes first and second components on which male and female fitting members of each of a plurality of pairs of fitting members are arranged, with a pair of first alignment keys formed in the first and second components as reference positions. The first and second components are coupled to each other by the female fitting member clamping an insertion portion of the male fitting member inserted between first and second clamping portions of the female fitting member arranged so as to face each other in a state where the pair of first alignment keys are positionally aligned. The first and second clamping portions are each bent so as to form one of protrusions toward one of surfaces thereof facing each other. A gap is formed in a distal end portion of each of the first and second clamping portions.

Abstract: A power conversion device includes: circuit boards; at least one engagement member configured to engage a male engagement member with a female engagement member to allow the circuit boards to be electrically connected, the male engagement member being connected to one of the circuit boards and having a substantially flat plate-shaped insertion portion, the female engagement member being connected to another of the circuit boards and having first and second clamping portions disposed to face each other, and the engagement of the engagement members being made by clamping the insertion portion by the clamping portions; a differential amplifier configured to measure a voltage across the engagement member; an arithmetic unit configured to estimate a resistance value of the engagement member based on the measured voltage; and a power conversion circuit controller configured to perform notification on condition that the estimated resistance value exceeds a resistance threshold.
