High frequency power transformers
General information
Power transformers insultate the net voltage from the final user but also modulate the input signals in order to get certain output power rating.
Therefore the design and manufacturing of power transformers is something that needs experience and special know-how, as these components, regarding weight volume and efficiency, turn out to be the critical points of the equipment in which they are mounted.
