Abstract

A busbar for power conversion applications that includes two planar conductors that have terminal locations; a first planar insulator located between the planar conductors; two impedances elements that are electrically connected to each of the planar conductors, wherein the impedance elements each extend in a plane that is non-coplanar from the planar conductors, further wherein the impedance elements are configured so as to define a gap between them; and a second planar insulator is located in the gap. A power conversion assembly that connects an energy source and a power switch to the busbar.
