Abstract

A power electronic assembly includes a pair of thermally and electrically conductive plates, and semiconductor switching elements positioned between contact surfaces of the pair of conductive plates. A first of the semiconductor switching elements is positioned at a first region of the conductive plates, and a second of the semiconductor switching elements positioned at a second region of the conductive plates. At least one of the conductive plates includes an aperture positioned between the first region and the second region of the conductive plates, such that in a compressed state, a contact surface of the conductive plate associated with the first region is substantially parallel to and offset from that of the second region in a direction parallel to the direction of compression.
