Abstract:
1. A DC bus bar structure for use in a power module, comprising: an elongated substantially planar first bus plate, the first bus plate comprising at least an upper surface; a first insulating layer overlying a portion of the upper surface of the first bus plate and exposing a wire bonding area on the upper surface, the bonding area extending along at least a portion of one edge of the upper surface of the first bus plate; and an elongated substantially planar second bus plate, the second bus plate comprising at least an upper surface comprising an exposed wire bonding area extending along at least a portion of one edge of the upper surface of the second bus plate, the second bus plate overlying at least a portion of the first insulating layer and positioned parallel to the first bus plate such that the upper surface of the first bus plate and the upper surface of the second bus plate are parallel and face a same direction, and where the second bus plate is spaced from the first bus plate by the first insulating layer; and wherein the first and second bus plates are physically positioned between a high side and a low side of the power module, a first set of wire bonds electrically coupling the bonding area of the first bus plate to one of the high side and the low side of the power module, and a second set of wire bonds electrically coupling the bonding area of the second bus plate to the other one of the high side and the low side of the power module.
