Abstract: A power converter includes a control circuit executing feedback control of a first inverter based on a detected value of a first sensor adapted to a first rotating electrical machine. The first sensor detects a current of a first busbar adapted to the first rotating electrical machine. The first busbar connects the first inverter and the first rotating electrical machine. A second busbar adapted to a second rotating electrical machine connects a second inverter and the second rotating electrical machine. The second busbar is arranged to be apart from the first sensor interposed with a converter busbar between the second busbar and the first sensor. A current of the converter flows through the converter busbar.

Abstract: A power converter includes an inverter, a converter, an electrical-machine busbar, an electrical-machine sensor, an electrical-machine-sensor housing, a converter, a converter busbar, a converter-sensor housing. The inverter supplies a three-phase alternating current to a rotating electrical machine. The converter converts a voltage between a direct current power supply and the inverter. The electrical-machine busbar passes a current between the inverter and the rotating electrical machine. The electrical-machine sensor detects the current flowing through the electrical-machine busbar based on a magnetic field. The electrical-machine-sensor housing accommodates the electrical-machine sensor and the electrical-machine busbar together. The converter sensor detects the current flowing through the converter based on a magnetic field. The converter-sensor housing is disposed apart from the electrical-machine-sensor housing, and accommodates the converter sensor and the converter busbar together.
