Power module for power converter, power converter, controller-integrated dynamoelectric machine

摘要

A compact, high-output power module and the like are supplied. A switching element group for at least one phase of a power conversion circuit including an H arm switching element and an L arm switching element incorporating a temperature sensor, a current detector for detecting a current of the power conversion circuit, and at least one phase A lead frame that electrically connects the switching element group and the current detector so as to form a circuit for a minute, an inner lead group that connects the upper surface electrode of each switching element to the lead frame, and a portion of the lead frame that exposes each part. The P potential lead and the N potential lead of the lead frame are partially exposed from the same surface of the mold member, and the L arm switching element is connected via the inner lead and the N potential lead. Connected to the outside, the H arm switching element is connected to the outside only through the P potential lead, and P Position current path from the lead to the N potential leads are arranged in a loop.
