Designing Flyback Transformer for Discontinuous Mode

WebSep 5, 2024 · Additionally, the transformer turns ratio needs to be set such that the reflected output voltage is less than the minimum input voltage. If not, the output voltage will be clamped and the transformer will not properly reset. As a result, the two-switch flyback is inherently limited to a maximum 50% duty cycle. WebJun 1, 2016 · From here the dutycycle works to create 12V output and the flyback converter isprimarily a buck converter. Can I arbitrarily select a turns ratio of 10, for secondary voltage range of 6V to 18V and ask the flyback converter act as a buck/boost to achieve desired 12V output?
