1. A power converter comprising:
an inverter configured to supply a three-phase alternating current to a rotating electrical machine;
a converter configured to convert a voltage between a direct current power supply and the inverter;
an electrical-machine busbar configured to pass a current between the inverter and the rotating electrical machine;
an electrical-machine sensor being a coreless sensor configured to detect the current flowing through the electrical-machine busbar based on a magnetic field;
an electrical-machine-sensor housing configured to accommodate the electrical-machine sensor and the electrical-machine busbar together;
a converter busbar configured to pass a current flowing through the converter;
a converter sensor being a coreless sensor configured to detect the current flowing through the converter based on a magnetic field; and
a converter-sensor housing disposed apart from the electrical-machine-sensor housing, the converter-sensor housing configured to accommodate the converter sensor and the converter busbar together,
wherein the converter busbar has a section extending in a perpendicular direction perpendicular to an extending direction of the electrical-machine busbar, and is disposed at a position apart from the electrical-machine busbar in the perpendicular direction.
