Abstract:
A power output stage having electrically conductive first and second power connectors, said output stage comprising;at least one electrically conductive first interconnect;at least one electrically conductive first tapered segment, said first interconnect mounted at an apex of said first segment;an electrically and thermally conductive substrate;a plurality of paralleled semiconductor devices electrically and thermally bonded to said substrate;a plurality of lead wires electrically conduct devices to said first tapered segment;a proximate driver board; andat least one electrically conductive second interconnect attached to said substrate, said semiconductor devices disposed relative to said first interconnect such that current flow paths between the apex and said semiconductor devices are each of substantially equal impedance, said semiconductor devices disposed relative to said second interconnect such that the current flow paths between said semiconductor devices and said second interconnect are each of substantially equal impedance, the intrinsic characteristics of said semiconductor devices dominate the impedance of said output stage, said devices driven by said proximate driver board.
