POWER CONVERSION DEVICE

摘要

Provided is a power conversion device which can reduce wiring inductance of the device as a whole while destruction of the power conversion semiconductor elements caused by surge voltage is suppressed. A power module (100) comprises a power module main unit (100a). The power module main unit (100a) includes: a P-side electrically conductive plate (3), a first N-side electrically conductive plate (4a), and a second N-side electrically conductive plate (4b) that are arranged with spaces therebetween within the power module main unit (100a); a P-side semiconductor element (5) that is arranged on the surface of the P-side electrically conductive plate (3); an N-side semiconductor element (6) that is arranged on the surface of the first N-side electrically conductive plate (4a) and is electrically connected with the P-side semiconductor element (5); and a capacitor (13) for suppressing surge voltage that is arranged so as to connect with the P-side electrically conductive plate (3) and the second N-side electrically conductive plate (4b), between the P-side semiconductor element (5) and the N-side semiconductor element (6), within the power module main unit (100a).
