Abstract:
To provide an inverter capable of suppressing insufficient cooling of a capacitor.SOLUTION: An inverter 10 comprises a heat sink 11, a power substrate 20, a control substrate, and a capacitor substrate 50. The inverter 10 also comprises a plurality of power elements. The plurality of power elements are separated into six power element groups and arranged. In each power element group, each power element comes into line. Each power element group is arranged at intervals. The inverter 10 further comprises a spacer 40 electrically connecting the power substrate 20 and the capacitor substrate 50. The spacer 40 comprises a main body 41 and a heat transfer unit 42. The heat transfer unit 42 is located outside the power element group in a power element arrangement direction, and arranged in a position in which it does not overlap the capacitor 54 when viewed from a plate thickness direction of the capacitor substrate 50.SELECTED DRAWING: Figure 6
