Abstract
A power module includes power switching devices that are electrically coupled in parallel to increase current capacity. The paralleled power switching devices are triggered by a common gate signal. Each of the power switching devices include a gate terminal, a current-sense terminal, and a Kelvin source/emitter terminal. The power module includes a plurality of magnetically coupled windings coupling the gate terminal, the current-sense terminal and the Kelvin source/emitter terminal of each of the switching devices to a gate driver circuit.
