Abstract
A power module includes a box-shaped smoothing capacitor (20) for smoothing a DC supply voltage to be externally applied to a power semiconductor device (5). The smoothing capacitor (20) is in contact with a side surface of a case frame (6) including a side (along which an N-terminal (8N) and a P-terminal (8P) are arranged) of a top surface of the case frame (6), and has a top surface level with the top surface of the case frame (6). An N-electrode (21N) and a P-electrode (21P) of the smoothing capacitor (20) are disposed on the top surface of the smoothing capacitor (20) and in proximity to the N-terminal (8N) and the P-terminal (8P) of a power module body portion (99), respectively. The power module can reduce a circuit inductance, is reduced in size and weight, and has good resistance to vibration.
