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