Abstract :
The role of leakage inductance in filter performance and current handling is discussed. It is demonstrated that leakage inductance is desirable. The underlying physics for the common mode (CM) inductor are reviewed. A model which enables the designer to predict the leakage inductance of the CM choke is presented. Experimental data and practical applications are presented. A core selection methodology which incorporates leakage inductance criteria has been defined. Example predictions are demonstrated
