Description
位相オフセット回路を使用して、ブリッジ・キャパシタの充電電流の位相と電力プレコンバータの出力電流の位相を合わせることにある。
簡単に述べると、ここで述べられている発明的構成による電源は、電源のフィルタ部を通って流れる全実効電流を減少させる。スイッチ・モード電源回路の動作はプレコンバータ回路の動作と同期し、その結果、スイッチ・モード電源回路が入力電流を引き入れる各期間の一部の間、入力電流はプレコンバータ回路からスイッチ・モード電源回路に直接に流れる。
ここで述べられている更に別の発明的構成による電源は以下のものから成る:整流手段;電力プレコンバータに結合されるエネルギー蓄積手段;電力プレコンバータとエネルギー蓄積手段に結合されるスイッチ・モード電源回路;および、電力プレコンバータの動作とスイッチ・モード電源回路の動作を同期させる手段。
ここで述べる更に別の発明的構成による電源は以下のものから成る:整流手段;整流手段に結合される電力プレコンバータ;電力プレコンバータに結合されるエネルギー蓄積手段;電力プレコンバータとエネルギー蓄積手段に結合されるスイッチ・モード電源;および、スイッチ・モード電源回路が入力電流を引き込む各期間の一部の間に電力プレコンバータから直接にスイッチ・モード電源回路へ電流を供給する手段。
