![]() I wonder if it can short the secondary leakage out as below (Note: The R2 can't be shorted, it should always exist at the left side of the red line). When it measure the "leakage inductance", it short the secondary.Which one this inductance conrrespond to in the text book above? The primary one only or the primary one add the reflected secondary one?.Primary, therefore this “leakage inductance” is shown on a schematicĭiagram as an additional inductance before the primary of an idealĪpparently, there is only one "leakage inductance" at one side in the figure above. The secondary winding acts as inductive impedance in series with the ![]() Any magnetic flux that does not link the primary winding to ![]() That results from the imperfect magnetic linking of one winding toĪnother. Leakage inductance is an inductive component present in a transformer You see, there are two separate inductance on each side, that is, the primary leakage inductance and the secondary leakage inductance.Īnd we reflect all the load at secondary to the primary side, then getĪll are easy to understand, there are two "leakage inductance", though you can reflect them to the same side, but in physics, there indeed are two "leakage inductanes".īut in the app note from a leakage inductance tester, it says ![]() It's apparent that the two leakage flux will create separate inductance on each side. Per this text book, it gives a schematic view of fluxes flow in the transformer: I'm a little confused about the transformer "leakage inductance" for days. ![]()
