Boost converter

Abstract

There is provided a boost converter. The boost converter comprises a reactor electrically connected with a power source; a semiconductor module configured to include a plate-like member and a terminal protruded from the plate-like member; a holder portion provided as a frame-like member, arranged to be adjacent to the reactor along either a longitudinal direction of a vehicle or a vehicle width direction, and configured to hold a plurality of the semiconductor modules inside of a frame of the holder portion such that the plurality of semiconductor modules are stacked and pressurized; and a first bus bar arranged to electrically connect the reactor with the terminal and provided with a current sensor that is configured to detect an electric current flowing from the reactor to the semiconductor modules. At least part of the current sensor is provided in the first bus bar such as to be placed inside of a range that is defined by respective ends of the holder portion in an array direction in which the reactor and the holder portion are arranged to be adjacent to each other. This configuration prevents increase of the dimension of the boost converter either in the longitudinal direction of the vehicle or in the vehicle width direction.
