HARMONICS IMPACT

HARMONICS IMPACT

The impact of harmonics over winding losses have already been analysed by Juan Gallego in his application note Impact of Harmonic Analysis in Magnetic Design. The objective of this paper is to show a real example case of how harmonics can considerably affect the performance of a transformer and to provide some guidelines for reducing such impact at the design stage.

Fringing flux effect in Inductance

Fringing flux effect in Inductance

The fringing flux is an effect that happens around air gaps when the magnetic cores are excited. The magnetic flux lines swell because the magnetic lines repel each other when passing through a nonmagnetic material, causing a decrease in the flux density. Many models have been developed along the years. In this app note six models are studied and compared against measurements, plotting the values and their relative error.

LEAKAGE INDUCTANCE IN TRANSFORMERS

LEAKAGE INDUCTANCE IN TRANSFORMERS

Designing a magnetic component with a specific leakage inductance can be challenging and difficult to predict as the theoretical results commonly differ form reality. The objective of this App Note is to show how to control the leakage inductance, and check the theoretical knowledge with experimental results.
