Primary transformer calculations
WebApr 24, 2006 · The following equations are frequently used to specify a flyback transformer. They are followed by a typical design example. Let V= L d j /d t , and V in,min =. (L p I pp f)/ (δ max ) Where V in = input voltage, V. L p = primary inductance, mH. I pp = peak current, A. δ max = maximum duty cycle, μs.

WebInductance in the primary of a transformer decreases as the load on the secondary increases. No it doesn't. It may seem like it does (because when loaded your transformer takes more current into the primary) but just imagine that the load you put on the secondary (say 1:1) ratio were applied to the primary - the current in the load would be the same (1:1 … WebParameters. Phase: Specify the phase arrangement. 1 Phase AC or 3 phase AC. Transformer rating (S): The tranformer rating in VA, kVA or MVA. Primary voltage (Vp): The rated …
