ルタ。[Claims for Utility Model Registration] A fundamental wave blocking filter that blocks the fundamental wave generated by the switching operation and a harmonic blocking filter that blocks the harmonics generated by the switching operation are installed between the AC input terminal and the rectifier. A noise blocking filter of a switching regulator is formed by interposing the fundamental wave blocking filter, and the fundamental wave blocking filter is constituted by a parallel resonant circuit in which a capacitor is connected in parallel to a line filter and resonates with the fundamental wave. A noise blocking filter for a switching regulator.
