Abstract
バーストモードを設けた同期整流型のＤＣ－ＤＣコンバータにおいて、二次側の電流が逆流しないようにする。 電圧変換用のトランス（２０）と、該トランスの一次側コイルと接続されたスイッチング素子（ＳＷ１）およびそのオン、オフ制御を行なう一次側制御回路（３０）と、二次側コイルと接続された同期整流用スイッチング素子（ＳＷ２）およびそのオン、オフ制御を行なう二次側制御回路（４０）とを備え、負荷が軽くなったときに一次側のスイッチング素子の制御信号をオフにするバーストモードを設けた同期整流型のＤＣ－ＤＣコンバータにおいて、バーストモードに入る際およびバーストモードから抜ける際に、一次側コイルと接続されたスイッチング素子をオン、オフ制御する制御信号のパルス幅がＰＷＭパルス本来の幅以下にならないようにするパルス幅保証回路（ＦＦ１）を設けるようにした。
