Power converter

摘要

The power converter includes a power conversion section which configures a circuit for power conversion, a power bus bar extending from the power conversion section, a terminal block, and a current sensor measuring current flowing in the power bus bar. The terminal block includes a mounting surface to which a terminal portion of the power bus bar is mounted. The mounting surface faces a direction substantially perpendicular to an arrangement direction in which the power conversion section and the terminal block are arranged. The current sensor is located at a side of a bottom surface on the opposite side of the mounting surface in the terminal block. The power bus bar includes: a sensor-surrounded portion surrounded by the current sensor; and an outer surface faced portion located between the sensor-surrounded portion and the terminal portion along an outer surface on the opposite side of the power conversion section.

主权项

1. A power converter comprising:
a power conversion section that configures a circuit for power conversion; a power bus bar that extends from the power conversion section in a first direction, the power bus bar including a terminal portion; a terminal block that is arranged side by side with the power conversion section in the first direction at a side in which the power bus bar is extended from the power conversion section, the terminal block including a mounting surface to which the terminal portion of the power bus bar is mounted, a bottom surface on an opposite side of the mounting surface, and an outer surface on an opposite side of the power conversion section, the mounting surface and the bottom surface being parallel to the first direction, the outer surface being parallel to a second direction perpendicular to the first direction; a current sensor that measures current flowing in the power bus bar, wherein: the mounting surface faces the second direction perpendicular to the first direction in which the power conversion section and the terminal block are arranged; the current sensor is arranged side by side with the terminal block in the second direction at a side of the bottom surface of the terminal block; the power bus bar further includes a sensor-surrounded portion surrounded by the current sensor and an outer surface faced portion located between the sensor-surrounded portion and the terminal portion along the outer surface of the terminal block in the second direction; and the power bus bar is formed into a U-like shape by the sensor-surrounded portion, the outer surface faced portion, and the terminal portion in such a manner that the sensor-surrounded portion faces the bottom portion of the terminal block in the second direction, the outer surface faced portion faces the outer surface of the terminal block in the first direction, the terminal portion faces the mounting surface of the terminal block in the second direction, and the terminal block is located inside the U-like shape of the power bus bar.
