Abstract
A power conversion device includes a multiphase power conversion circuit, a plurality of bus bars which are arranged adjacent to each other, phase currents of the multiphase power conversion circuit flowing through the plurality of bus bars, respectively, a single current sensor configured to detect any of the phase currents in the plurality of bus bars, and a housing which houses the multiphase power conversion circuit, the plurality of bus bars and the current sensor, in which the current sensor includes a magnetic core through which the plurality of bus bars are inserted such that flow directions of the phase currents are the same direction, and which has a single magnetic gap, and a Hall element inserted in the magnetic gap.
