A POWER MODULE FOR CONVERTING DC TO AC

摘要

A power module (220) for converting direct current to alternating current comprising a semiconductor switching circuit device (240), a substrate (248) onto which the switching circuit device (240) is physically and electrically coupled without wirebonds, a plurality of leadframe terminals (234a-234i) physically and electrically coupled to the substrate (248), and a cover (238) including an opening (243) exposing a bottom side of the substrate (248) and including a wall portion (231) oriented generally orthogonally relative to the substrate (248) with at least some of the leadframe terminals projecting outwardly from the wall portion (231). The leadframe terminals projecting outwardly from the wall portion (231) may include an affixed portion (233) coupled to the substrate (248) and an extending segment (237) lying in a plane above the affixed portion (233) with the extending segment (237) projecting outwardly from the wall portion (231) and the cover (238) encapsulating the affixed portion (233) whereby the extending segment (237) is spaced from a plane defined by the bottom side of the substrate (248).
