Без указанногоPower Specialist’s App Note Book- This report presents a comprehensive analysis, modeling, simulation, and design optimization of the self-oscillating flyback converter, which is also known as the Ringing-Choke Converter (RCC). The self-oscillating flyback converter is a very popular topology in cost-sensitive applications such as, for example, auxiliary power supplies and mobile phone chargers due to a low component count. As a result, this circuit is designed into numerous Delta power supplies and chargers.
