WebDec 19, 2016 · The bottom line is that choice of turns ratio, via VOR choice, is a decision you need to make to balance the ideal operating range for your duty cycle against peak … 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.
WebJul 29, 2024 · Finally, you will see in controllers specs for flyback that the maximum duty ratio is often in the range of 80-90%. The best is to create a sheet with a solver and play on the different turns ratio options to see hows the other parameters are affected. It is an iterative process for sure. WebIf the current is specified for the secondary, then this can be reflected back and computed for the primary by using the turns ratio. Sometimes data sheets only specify the Volt-Time product. This is the maximum amount of time that the transformer can have a constant voltage applied to it.
