The reason for this is that the sheet laminated core can reduce another type of iron loss – eddy current loss.

Transformers classified as Class II or Class III are used for circuits classified as Class II or Class III, respectively, according to the National Electrical Code, ANSI/NFPA 70. The main purpose of these connectors is to connect sinusoidal power supplies.

Laminating steel sheets are commonly used for transformer cores. Laminating containing silicon has a silicon content of 0.8%~4.8%. Due to the fact that laminate steel is a magnetic material with strong magnetic permeability, silicon steel is used as the iron core of the transformer.

Generally, bobbin transformers are two-winding transformers in which the primary and secondary coils are wound side by side on separate bobbin separated by an insulating barrier to create a two-winding transformer.

Among the transformer losses there are iron losses, copper losses, hysteresis losses, eddy current losses, stray losses, dielectric losses, and other types of losses. In transformers, hysteresis losses are caused by changes in the magnetic field of the transformer core, whereas copper losses are caused by the resistance of the transformer windings.

How do you judge if the quality of a high frequency transformer is good or not when you buy one?You can easily get it by following the following 3 steps:

Transformers with high frequency exceeding the intermediate frequency (10 kHz) can be used in high-frequency switching power supplies as high-frequency switching power supply transformers.
