WebNov 3, 2016 · It's all related to flyback action itself. Flyback action cannot be initiated and completed, because there's no load. Remember how flyback converters work: Energy stored in primary winding will be transfer to the "load". No load, no transfer, no flyback action. The solution is putting a "dummy load" in the converter. WebApr 26, 2016 · Two common locations in a flyback converter where excessive ringing occurs.
