電子機器の小型化・低待機電力トレンドと新伝導 EMI 規格を両立するためのスイッチング電源の低ノイズ化に関する実験的検討

抄録

In the power electronics field, the movement that the EMI noise standard is revised is being carried out by IEC. In this paper, we investigate measures to apply frequency spreading to the frequency range and measurement conditions of the new standard(below 150 kHz), and consider measures that can achieve both noise reduction performance and miniaturization of electronic equipment and low standby power performance.
