Anyone noticed yet the High Frequency transformers - sometimes called switch mode HF transformers - you see on the PCB's of nowadays electronic equipment?
This is one http://www.mcemagnetics.com/images/horz%20E%20core%20UL%20x2.jpg and http://avanteck.com/images/images%20for%20item%20pages/power/smallB8846435231.jpg
This is a type you often see in AC's http://www.tauscher.com/hf_EDT-44-stehend.jpg
In every decent AC, you will find some of these.
Sometimes a 2 kW transformer is crunched in a housing of only 2 inch high on a footprint of only 3 x 2 inch and it weighs almost nothing compared to a normal transformer.
A normal 2 kW transformer is a real heavy peace of copper and iron
Does anyone know of a link of the working principle?
