Flyback inductance

WebAll circuit values such as inductance, peak and rms currents and turns ratios must be defined before beginning the magnetics design procedure. A practical design example of a flyback transformer design using this procedure is in the paper: "150 Watt Flyback Regulator". Step 1. WebThe flyback topology (Figure 1A) results in significant cost and space savings for multiple output power supplies with high output voltage for power levels up to 100W. This …

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). 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. WebSep 18, 2024 · 1 Answer Sorted by: 5 The primary has an inductance of 38 uH and couples to the secondaries with a turns ratio of 2:1 and 2:1.1. 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. porsche design puma shoes

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.
