Influence of the Parameters of Disk Winding on the Impulse Voltage Distribution in Power Transformers

Overvoltage distribution along the transformer winding must be uniform to certify the safety of the operation of the power transformer. Influence of the parameters variation on the impulse voltage distribution (IVD) in disk winding transformer is going to be analyzed which hasn’t been analyzed on this type of winding in the previous papers. In this research, a transformer with disk winding and ...

High frequency winding design for planar switch mode transformers

Switch mode power supplies as a mass produced article leave room for optimization especially at the voluminous magnetic components. Hereby planar component designs can reduce the overall height of the power supply and give it a more compact design. Since cores are available in standard sizes the optimal winding layout has to be found. Due to increased parasitic capacitance interleaving is not a...

Linear Analysis Part II

The objects in this course are infinite dimensional vector spaces (hence the term “linear”) over R or C, together with additional structure (a “norm” or “inner product”) which “respects” in some way the linear structure. This additional structure will allow us to do “analysis”. The most pedestrian way to understand the last sentence is that it will allow us to “take limits”. In fact, the extra ...
