Abstract
A power module includes a plurality of switching devices. The switching devices are electrically coupled in parallel and triggered by a common gate signal. The switching devices are further attached to a substrate that includes a first coil and a second coil formed around a common axis to define a common mode choke in a gate path and a Kelvin source/emitter path of each of the switching devices.
