Title: 力率補正用途
IPC: H02M1/00
Filed: 2000-04-27
Abstract: (57)【要約】
商業的に利用可能な遷移モード力率補正集積回路は、電力出力回路におけるＭＯＳＦＥＴを制御するのに使用される出力ピンと、ピーク電流を設定するのに使用される倍率器入力ピンとを有する。入力ライン電流におけるゼロ交差歪みは、前記倍率器入力ピンに印加される整流ライン電圧の部分の範囲を減少することによって、大幅に減少する。ツェナーダイオードのようなクランプ装置を、前記整流ライン電圧を感知するのに使用される分圧器に加え、前記倍率器入力部におけるピーク値を、前記整流ライン電圧がある値を超えた場合、クランプするようにして、前記範囲を減少させてもよい。他の技術は、前記整流ライン電圧を感知するのに使用される分圧器におけるインピーダンスの値を変化させる。前記分圧器インピーダンスにおける変化を、トランジスタを使用し、抵抗を前記分圧器に対して切り替え、検出器回路を使用し、この信号トランジスタを前記整流ライン電圧の関数としてターンオン又はターンオフすることによって達成してもよい。
