Abstract
A conductive noise suppressor for suppressing worsening of noise due to the frequency of conductive common mode noise is suppressed is provided in an embodiment of the disclosure. The suppressor includes a first coil part for detecting a noise current in a common mode flowing through a power supply line for supplying an alternating current, coils serially inserted on the power supply line, a second coil part including a coupling coil magnetically coupled to the coils and a current supplier for supplying a noise current detected by the first coil part and a current set for a voltage generated across the coupling coil to the coupling coil.
