Abstract:
1. An electronic assembly for an inverter, the electronic assembly comprising: a substrate having a dielectric layer and metallic circuit traces; a plurality of terminals for connection to a direct current source; a first semiconductor and a second semiconductor mounted on the substrate and coupled together between the terminals of the direct current source; and a primary metallic island located in a primary zone between the first semiconductor and the second semiconductor, the primary metallic island being separate from the first semiconductor and the second semiconductor, and the primary metallic island having a greater height or thickness than the metallic circuit traces, the primary metallic island providing a heat sink to radiate heat; a first enclosure portion overlying the substrate and the primary metallic island; wherein the heat is conducted away from the primary metallic island through a first enclosure portion in contact with, above or in close proximity to the primary metallic island, and wherein the first enclosure portion comprises a group of coolant channels or micro-channels within an adjoining cover or enclosure in contact with, above or in close proximity to the primary metallic island for transfer of the heat from the primary metallic island.
