Abstract: A power module packaging structure includes a first conducting layer, a first insulating layer, a second conducting layer, a first power device, and a first controlling device. The first insulating layer is disposed above the first conducting layer. The second conducting layer is disposed above the first insulating layer. The first power device is disposed on the first conducting layer. The first controlling device is disposed on the second conducting layer and used for controlling the first power device. The first conducting layer, the second conducting layer, the first power device, and the first controlling device form a loop. A direction of a current which flows through the first conducting layer in the loop is opposite to a direction of a current which flows through the second conducting layer in the loop.
