Web15 apr. 2011 · 636. 2. berkeman said: The Lm is in parallel with an ideal transformer, not any other "inductance". And the Lk is in series, as it is usually modeled. The secondary voltage is "mirrored" or sensed because of the output diode. When the output winding's voltage is below the output voltage plus a diode drop, there is no current flowing in the output. WebThe standard method for measuring leakage inductance of magnetic components is based on the fact that if a winding is shorted, the field applied by another winding will then be automatically canceled out by the opposite field generated by the shorted winding (this is the assumption, but in practice the mutual flux is not canceled out completely).
