摘要： According to the present invention, a power conversion device comprises a plurality of sets of power conversion circuits that convert AC to DC or DC to AC by the switching action of a plurality of semiconductor elements, the semiconductor elements that constitute the plurality of sets of power conversion circuits are mounted on a common cooling unit having a heat sink section and heat discharging section. By smoothing out the apportionment of heat loss applied to the plurality of coolers constituting this cooling unit, a cooling construction of the minimum necessary size can be achieved and miniaturization and weight reduction can be realized.

摘要： A capacitor 8 is connected in parallel to both ends of two series-connected semiconductor devices 1, the connecting terminals of the capacitor are arranged so that they become immediately close to the terminal positions of the semiconductor devices 1, inductance of a loop circuit comprising the semiconductor devices 1 and capacitors 8 is suppressed o below 250 nH and thus, a semiconductor switching circuit is constructed. Three sets of this semiconductor switching circuit are connected in parallel with each other, both ends of upper and lower series-connected semiconductor devices in the semiconductor switching circuit are made the main circuit inputs or outputs and the intermediate connecting point of the upper and lower semiconductor devices is made the main circuit output or input and using the capacitors 8 as filter capacitors and surge voltage absorbing capacitors and thus, a power converter is constructed by only two kinds of capacitors and semiconductors.
