Abstract

An electronic component includes: a laminate busbar structure comprising at least two busbar layers separated by an insulating layer; a transistor connected to the laminate busbar structure on a first side thereof; and a capacitor that is mounted on the first side of the laminate busbar structure and is positioned further away from the laminate busbar structure than the transistor, the capacitor having respective planar terminals parallel to each other and perpendicular to the laminate busbar structure, each of the planar terminals comprising a rectangular member with one side thereof connected to the capacitor and an opposite end connected to a corresponding one of the busbar layers.

First claim

What is claimed is:

1. An electronic component comprising:
a laminate busbar structure comprising at least two busbar layers separated by an insulating layer;
a transistor connected to the laminate busbar structure on a first side thereof; and
a capacitor that is mounted on the first side of the laminate busbar structure and is positioned further away from the laminate busbar structure than the transistor, the capacitor having respective planar terminals parallel to each other and perpendicular to the laminate busbar structure, each of the planar terminals comprising a rectangular member with one side thereof connected to the capacitor and an opposite end connected to a corresponding one of the busbar layers.

2. The electronic component of claim 1 , wherein the capacitor is enclosed in a housing and wherein the planar terminals extend outside the housing.

3. The electronic component of claim 2 , wherein each rectangular member extends from end to end of the housing.

4. The electronic component of claim 2 , further comprising a support structure for the rectangular members extending from the housing toward the laminate busbar structure.

5. The electronic component of claim 4 , wherein the support structure holds the planar terminals by their edges and exposes outward facing surfaces of the rectangular members.

6. The electronic component of claim 4 , wherein a portion of the support structure insulates the planar terminals from each other.

7. The electronic component of claim 4 , wherein the support structure and the rectangular members are configured to position a busbar locating component relative to the electronic component, the busbar locating component configured to have the laminate busbar structure attached thereto.

8. The electronic component of claim 1 , wherein the electronic component is an inverter that includes multiple transistors, the busbar layers include at least first and second DC busbar layers and an AC busbar layer, and the capacitor is a DC link capacitor for the inverter.

9. The electronic component of claim 8 , wherein each of the planar terminals has multiple leads at the opposite end of the rectangular member, the leads connecting the respective planar terminal to the corresponding one of the busbar layers.

10. The electronic component of claim 9 , wherein each of the busbar layers has openings with corresponding tabs extending from peripheries thereof, and wherein each of the tabs is configured to align with and contact a corresponding one of the multiple leads.

11. The electronic component of claim 9 , wherein the leads of the respective planar terminals are paired and positioned adjacent a respective one of the multiple transistors.
