Abstract: A power module includes first and second electrode terminals adapted to electrically connect to a power source, a first switch element, a second switch element, a first Kelvin source pin, and a second Kelvin source pin. The first switch element is electrically connected to the first electrode terminal The second switch element is electrically connected between the first switch element and the second electrode terminal and includes a drain and a source electrically connected to the first switch element and the second electrode terminal respectively. The first Kelvin source pin is electrically connected to the source of the second switch element and is adapted to receive a gate drive signal for driving the second switch element. The second Kelvin source pin is electrically connected to the source of the second switch element and is configured to be electrically connected to a snubber circuit.
