PROBLEM TO BE SOLVED: To prevent switching noise of a switching element or the like, which is transferred to a metallic chassis through a stray capacity between a reactor and the metallic chassis, from being radiated through a pipeline and the like. SOLUTION: Noise, propagated from a switching element 23 or the like to a reactor 24, a stray capacity 23 and a metallic chassis 34, can be prevented by a ferrite core 35, inserted into the connecting line 36 of the reactor 24 through a common mode. |
