Claim of US Patent No. 10,091,903

1. A power conversion device, comprising:a power semiconductor module that converts a DC current into an AC current;
a plate conductor that transfers the DC current or the AC current;
a resin sealing material that seals the plate conductor; and
an electric component that is used to control the power semiconductor module,
wherein the resin sealing material includes at least one supporting member that supports the electric component,
wherein the plate conductor is buried in a portion of the resin sealing material that is disposed to face the electric component,
wherein the at least one supporting member includes a first supporting member to support a driver circuit board and a second supporting member to support a current sensor,
wherein the resin sealing material includes a first surface equipped with the first supporting member and a second surface equipped with the second supporting member, in which the first surface and the second surface are disposed to form an angle with respect to each other,
wherein the resin sealing material includes a bent portion that connects the first surface and the second surface, and
wherein the plate conductor is at least partially disposed within the bent portion of the resin sealing material.
