WebAug 30, 2012 · A larger duty ratio D corresponds to a larger coupled-inductor turns ratio n, which results in a lower voltage stress on free-wheeling diodes D 1 and D 2. In order to accommodate variations of loads, a proper turns ratio n of the coupled inductors is needed. From Figure 10, we can obtain a proper coupled-inductor turns ratio n = 8. WebBasically, flyback converter can be derived from buck-boost converter, in which the inductor split to form a transformer. The transformer with specified turns ratio steps up or down the input voltage with isolation. The energy transfer from primary to secondary is controlled using a switch connected to primary. phoenix walk in and health centre
