<P>PROBLEM TO BE SOLVED: To provide a power module which can easily be reduced in size, and a power conversion device. <P>SOLUTION: The power module 1 comprises a switching element 2, a cooler 3 in which a coolant for cooling the switching element 2 flows, and a capacitor 4 which suppresses a surge voltage generated by the switching of the switching element 2. The capacitor 4 is arranged in a position which crosses a virtual plane S formed by extending the contact face of the switching element 2 and the cooler 3. The cooler 3 is arranged so as to contact with both main faces of the switching element 2, and the capacitor 4 is preferably arranged in a position which crosses the two virtual planes S formed by extending a pair of contact faces between the cooler 3 and the switching element 2. <P>COPYRIGHT: (C)2009,JPO&INPIT |
