| Abstract(in English) | Recently, conducted emission resulting higher harmonic of switching frequency is increasing due to higher switching of power converter circuit. Therefore, expansion of an attenuation bandwidth of a common-mode choke coil is required. We developed the quasi-distributed constant line filter which has a wideband attenuation characteristic. To improve an attenuation bandwidth at low frequency, high permeability magnetic core was used. The characteristic grounding terminal which can produce a quasi-distributed constant line at windings was attached to improve an attenuation bandwidth at high frequency. The attenuation band over 40 dB could be expanded from 200 kHz – 3 MHz to 80 kHz – 17 MHz by optimizing a ratio of grounding capacitance to parasitic capacitance of windings. |
