Flyback application circuit

WebAug 28, 2024 · Flybacks actually regulate the output and require control to cross the isolation barrier. They also have large voltage spikes that are intrinsic to the design and require snubbing. This increase in complication gives you more precise regulation, meaning you can use it at higher power levels. You can use Flyback transformers in many applications, including: 1. DC-DC power supplies 2. Telecom 3. LED Lighting 4. Power over Ethernet (PoE) 5. Capacitor charging 6. Battery charging 7. Solar Microinverters 8. AC-DC power supplies Off-the shelf flyback transformers are available for many applications … See more A flyback transformer is a coupled inductor with a gapped core. During each cycle, when the input voltage is applied to the primary winding, energy is stored in the gap of the core.
