Claim 0:
1. A switching device configured to be connected to an external power supply, and provided with a plurality of power conversion circuits, the switching device comprising:
a switching circuit configured to switch a connection of the plurality of power conversion circuits; and
a noise filter that includes a plurality of capacitors configured to remove noise,
the external power supply being a power supply selected from a multiple-phase power supply and a single-phase power supply,
the plurality of power conversion circuits respectively corresponds to phases of the multiple-phase power supply,
the plurality of capacitors respectively corresponds to the phases of the multiple-phase power supply,
in a case where the external power supply is the multiple-phase power supply, the switching circuit connects a first power conversion circuit of the plurality of power conversion circuits to a first phase of the external power supply through a first capacitor of the plurality of capacitors, and connects a second power conversion circuit of the plurality of power conversion circuits to a second phase of the external power supply, through a second capacitor of the plurality of capacitors,
in a case where the external power supply is the single-phase power supply, the switching circuit connects the first power conversion circuit and the second power conversion circuit to the first phase of the external power supply through the first capacitor.
