Current starts to flow through the primary, and the diode on the secondary side is reverse biased due to the transformer polarity. Therefore, all the energy is stored to the ...
Web2 AC Modeling of Power Stage in Flyback Converter 1.1 How it Works In a flyback converter, when the current ramps up in the primary, energy is built up in the transformer core. When the FET switches off, this energy is dumped into the secondary, allowing current to flow in the secondary, so the primary current collapses immediately to zero. philip westmorelandWebFlyback transformers are used to provide voltage transformation and circuit isolation in flyback converters. Flyback transformers are the most popular choice for cost-effective, high-efficiency isolated power supply designs … philip westcottWebAlthough flyback converters are very popular, this topology has practical limitations.
