Abstract

　回路面積およびコストアップを小さく抑えたまま、負荷に安定して電力を供給することができる給電システムおよび電圧安定化方法を提供する。絶縁コンバータ１０と非絶縁コンバータ２０との間に電圧安定化回路４０を配置し、絶縁コンバータ１０からの入力電圧Ｖｉｎが上昇した場合、コンデンサ４１を介してトランジスタ４５にベース電流Ｉｂを流すことによりトランジスタ４１のコレクタにベース電流Ｉｂのｈｆｅ倍のコレクタ電流Ｉｃを流すことにより、コンデンサ４１の静電容量Ｃに対して、トランジスタ４５の電流増幅率ｈｆｅ倍に相当する静電容量を有するコンデンサが、電力供給ライン３１とグランド３２との間に挿入された場合とほぼ同じ効果を生じさせる。
