フェーズ･シフト･ゼロ電圧スイッチング･フルブリッジ･コンバータでは、フルブリッジの2つのレッグが2つの方形波でスイッチングされます。フェーズ･シフトはコンバータの制御ループによって変調され、生成される方形波は、1次/2次絶縁と電圧スケーリングを提供するトランスの1次側に供給されます。トランジスタの静電容量とトランスの漏れインダクタンス間の寄生共振を利用して、1次側の4つすべてのスイッチでソフト･ターンオン（理想的にはゼロ電圧スイッチング（ZVS））を実現します。また、低負荷時のZVS範囲を拡大するため、トランスの1次巻線と直列に共振インダクタを導入します。

ZVSはスイッチング損失およびストレスの低減に役立つ上、1次スナバを不要にします。また、より高いスイッチング周波数を可能にし、より高効率･高電力密度のコンバータを設計する上で役立ちます。したがって、このコンバータは大電力（600W超）の高周波アプリケーションに最適です。

STは、各種の先進的なデジタル･コントローラやダイオード、固有ダイオードの逆回復時間を向上させたパワーMOSFETを提供しています。STは、高性能マイクロコントローラSTM32とさまざまな専用ペリフェラル（高分解能PWMタイマや高速ADコンバータなど）に加え、ハードウェアとソフトウェアの評価および開発ツールやリファレンス設計の提供により、開発者がフルブリッジ･フェーズ･シフトZVSコンバータの利点を最大限に活用できるようにサポートしています。
