Abstract
A power converter assembly includes a heat sinking plate, a circuit board structure having a side that faces and is spaced by a gap from a surface of the heat sinking plate that is nearer to said side, a relatively thin, high heat density, dissipative semiconductor component mounted on said side, an encapsulating material filling the gap, and relatively taller, lower heat density, components mounted on the other side of the circuit board, the gap being characterized by an average thermal-resistance of less than 1° C.−in /Watt.
