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.
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.
Our annual event served as an international platform to bring together experts from the power electronics and magnetics industry.
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.
In this app note we are going to prove the effectiveness of Frenetic AI calculating the parasitic capacitance comparing Frenetic estimation with the theoretically calculated using different models and real measurements.
In this application note a comparison of Phase Shifted Full Bridge (PSFB) and Full Bridge LLC (FB-LLC) converters will be presented.
The objective of this App Note is to compare two winding losses calculation models: the classical Dowell one-dimensional (1-D) model and a twodimensional (2-D) model, that takes the edge effect into consideration.
In this app note it will briefly commented some key aspects to take in consideration for the design of the Full Bridge transformer. It will consider a secondary side with center tap, but it can be considered for a single secondary winding.
As part of Frenetic's hardware testing of magnetic components, a magnetic flux measurement circuit has been developed.
In this application note common-mode noise reduction is discussed.
In this App Note hysteresis losses will be discussed.
