Classification: CPC H | IPC H

Claim 3:
4. An electric power conversion device for a plurality of phases, comprising:
the electric power line; and
the power module according to claim 1,
wherein:
the power module is placed for each of the plurality of phases;
the power module placed in a first phase among the plurality of phases is a first power module;
the power module placed in a second phase among the plurality of phases is a second power module;
in the first power module, an impedance of an electric path from the positive electrode terminal to the upper arm is an in-phase upper impedance;
an impedance of an electric path from the positive electrode terminal corresponding to the first power module to the upper arm corresponding to the second power module is an interphase upper impedance; and
the interphase upper impedance is higher than the in-phase upper impedance.
