WebThe transformer plays a key role in the operation of the converter and the objective of this application note is to understand the most important parameters and design trade-offs to be taken. 1. Leakage Inductance. The leakage inductance is a measure of how well or bad coupled is a transformer. The higher the value the worst the coupling and ... WebMagnetizing inductance is the inductance that couples between the input and output winding(s), while the leakage inductance is the inductance that does not couple. The most common technique to measure is to use the open/short measurement. When you measure the primary winding when the secondary is open the magnetizing and leakage …
