17. A control board for supplying current to a stator included in an electric motor, the control board comprising:
a high-voltage circuit connected to a high-voltage power supply; and
a low-voltage circuit connected to a low-voltage power supply, wherein
the high-voltage circuit includes an inverter to convert an input direct-current voltage into an alternating-current voltage and supply the alternating-current voltage to the stator,
the low-voltage circuit includes a control circuitry to control the inverter, and
a first inductor is disposed on a low-voltage power-supply line that is a line connecting the low-voltage power supply and the low-voltage circuit.
