Abstract

　交流入力電源（Ｖａｃ）を全波整流するダイオードブリッジ（Ｂ１）を備え、その出力電圧をスイッチングするスイッチング素子（Ｑ１）、スイッチング素子（Ｑ１）により断続される電流を通電するとともに励磁エネルギーを蓄積・放出するインダクタ（Ｌ１）、ダイオード（Ｄ１）、および平滑コンデンサ（Ｃ１）によって昇圧チョッパ回路を構成し、ディジタル信号処理回路（１３）で入力電圧（Ｖｉ）の位相を検出し、その位相に応じてスイッチング素子（Ｑ１）のスイッチング周波数を変調する。これにより、入力電圧に依存することなくスイッチング周波数を適宜変調できるようにして、スイッチング周波数およびその高次周波数成分でのピーク状に発生するＥＭＩノイズを抑制しつつ広範囲な入力電圧に対応させる。
