Title:
CONDUCTIVE NOISE SUPPRESSION DEVICE, POWER CONVERSION DEVICE, AND MOTOR DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/208057
Kind Code:
A1
Abstract:
Provided is a conductive noise suppression device which suppresses noise deterioration caused by a frequency of conductive common mode noise. A suppression unit (100) comprises: a first coil unit (110) for detecting a noise current of a common mode that flows in a power line for supplying an alternating current; a second coil unit (120) having coils (L2R, L2S, L2T, and L2N) which are inserted into a power line (140) in series, and a coupling coil (L2A) which is magnetically-coupled to the coils (L2R, L2S, L2T, and L2N); and a current supplying unit (130) which supplies the coupling coil (L2A) with the noise current that is detected by the first coil unit (110) and a current that is set to a voltage generated in the coupling coil (L2A).
