The Leakage Inductance Model of Frenetic Online

Frenetic Webinar Series: The Leakage Inductance Model of Frenetic Online

Jul 16, 2024 06:00 PM CET

Transformer leakage inductance is crucial in many topologies such as flyback converters, dual active bridge converters, and resonant converters impacting operating parameters such as switching behaviour, overvoltage, and losses. Hence, the power electronic designer needs an accurate prediction of the transformer leakage inductance in the design stage. Frenetic just launched a new leakage inductance model to its online simulator. This model is based on a Quasi-3D (Q3D) modelling approach employing analytical solutions to the Maxwell equations. The model was verified with measurements on transformer prototypes and its accuracy is in the range of geometrical and measurement uncertainties.

This webinar presents the Q3D leakage inductance model and discloses its derivation, strengths, and limitations. We will present a live example of leakage inductance calculation in the Frenetic Simulator.
