Webcoupled inductors The transformer used in the Fly-Buck topology is a coupled inductor or a Flyback type transformer. It stores energy just like an inductor in a buck converter. Transformers used in forward, half-bridge, or full-bridge topologies store no or negligible amount of energy and are not suitable for a Fly-Buck topology. WebThese transformers are designed to meet UL, CSA, VDE, and IEC safety requirements and can meet RoHS requirements. In addition, Vishay manufactures signal transformers, audio transformers, and RF transformers that provide safety isolation. how to remove yellow stains from clothing
