Abstract
Provided is a noise suppression device capable of suppressing a common mode current with higher certainty. The noise suppression device includes a common mode coil connected between a power supply and a control device; and an electronic device which is connected in parallel with the common mode coil and in which a low frequency current of a current flowing between the power supply and the control device flows. In the noise suppression device, the low frequency current of the current flowing between the power supply and the control device flows in the electronic device. It is therefore possible to suppress the common mode current with higher certainty.

A noise suppression device comprising:
- common mode coils connected to each phase of plural phases between a power supply and a control device;
- and
- an electronic device which is connected in parallel with only one of the common mode coils and in which a low frequency current of a current flowing between the power supply and the control device flows.
