Abstract: A power module is disclosed and includes an upper surface for receiving multiple input signals, a lower surface for outputting multiple output signals, a top layer circuit board, a bottom layer circuit board and a middle layer. The top layer circuit board includes a first surface and a second surface disposed opposite to each other, and multiple electronic devices. The first surface forms the upper surface, and multiple first signal connection parts are disposed on the first surface for receiving the multiple input signals. The bottom layer circuit board includes a third surface and a fourth surface disposed oppositely. The fourth surface forms the lower surface, and multiple second signal connection parts are disposed on the fourth surface for outputting the multiple output signals. The middle layer is disposed between the top layer circuit board and the bottom layer circuit board.
