Simulation-based Improvement of Analytic Self-inductance for E and PQ Cores

Finite element analysis for inductive components is a well-established and precise development method. For faster predevelopment and easier to use techniques, a robust and low-computational alternative is sought. Corrected analytical calculations based on simulation results allow rapid testing for multiple parameter variations and finding an optimal initial design. This study shows the possibilities and limitations of such a correction and its advantages over complex simulations in some use cases.
