力率補正は、入力電流を可能な限り正弦波に近づけることで、高調波歪みとそれに伴う損失を低減し、AC回路の力率を1に近づけるための技術です。単相の力率改善回路は、比較的大電力のスイッチング電源（SMPS）のフロントエンドに配置されます。この回路は、特定の要件を満たしたさまざまな設計トポロジで利用することができます。高い電力密度を実現するには、複数の小さなインタリーブ段を持つインタリーブ･アーキテクチャが有効です。また、ブリッジレス･トポロジの実装によって、力率改善回路（PFC）とフロントエンド整流器の全体効率をさらに高めるとともに、ライン電流経路内の半導体デバイス数を最小限に抑えて、導通損失を低減することもできます。続きを読む
