Flyback duty 50%
WebCurrent mode switching regulators which operate with a duty cycle greater than 50% and have continuous inductor current can exhibit a duty cycle instability known as subharmonic oscillations. This effect is not harmful to the regulator and in many cases it does not even affect the output regulation. WebIf it helps, you could look at a flyback transformer as a boost converter. The voltage rise is due to the turn ratio and due to the inductance in the same way a boost converter works. ... and get a better result with duty closer to 50%. (Edit: and voltage ratio closer to the turns ratio) Reply More posts you may like. r/AskElectronics ...
