Flyback inductance

WebFlyback converters are a common design choice for low-power (<100 W) converters. At low power it is more difficult to achieve high efficiency because otherwise negligible … WebSep 5, 2024 · These variations of the flyback converter use nondissipative clamping techniques to recycle leakage energy and improve efficiency. In the standard form of a flyback converter, the leakage inductance of the transformer creates a voltage spike on the drain of the primary field-effect transistor (FET).

The 2:1 coupling means that the secondary inductance is ( 1: 2) 2 x 38 uH = 9.5 uH. The other secondary has a turns ratio slightly less (2:1.1) and therefore has an inductance of 11.5 uH.

WebApr 5, 2024 · The flyback transformer then, which is this two winding magnetic device, can be modeled in the same way as the usual transformer, with an ideal transformer and an magnetizing inductance put in parallel. But now we're using the magnetizing inductance as the actual physical inductor in our converter. And this inductor is designed to store energy. WebFlyback topologies are practical and lowest cost for systems up to power levels of 100W. Above this power level other methods such as forward converters become more cost …

This … WebFeb 11, 2016 · In a flyback transformer design you are storing energy in the primary then releasing it to the secondary. If you have leakage inductance, there is energy stored in the primary that doesn't get coupled to the secondary. This uncoupled energy has to be "burned off". This is where inefficiencies can be seen.
