Noise suppression device and air conditioner

摘要

OF THE INVENTION In a conventional noise suppression device comprised of a common mode coil, it 5 is necessary to increase the number of turns on the common mode coil or to increase the size of the common mode coil to obtain a sufficient amount of inductance required for noise suppression as the level of generated noise increases. A magnetic body 23 formed in a ring shape forming a hollow part 24 therein, power signal lines 7a and 7b wound around the magnetic body 23 through the hollow part 24, and a ground line 15 passing 10 through the hollow part 24 of the magnetic body 23 are provided for suppressing a noise current 18 and a noise current 19. ec
