Claim Text:
1. A power module comprising: a first substrate comprising at least a first electrically-conductive layer; a second substrate comprising at least a second electrically-conductive layer, the first and second substrates being stacked on each other; a scalable network of power semiconductor switches arranged on at least one of the first and second substrates; and a first power bar and a second power bar, wherein the first power bar and the second power bar are respectively connectable to the first and second electrically-conductive layers through respective electromechanical interfaces arranged at selectable interface locations along the first and second electrically-conductive layers, the interface locations and/or type of interface being selectable based on the arrangement of the scalable network of power semiconductor switches, wherein the first and second electrically-conductive layers are disposed on mutually opposed surfaces of a dielectric layer having a thickness chosen to effect a level of coupling between respective source and return current paths provided by the first and second electrically-conductive layers, the level of coupling arranged to increase the mutual inductance within said power module.
