What is the function of the transformer core? And what are the iron cores stacked with silicon steel sheets for?
The core of silicon steel sheet is mainly to reduce eddy current and disperse electric field eddy current.
In an electric field, if the eddy current is too large, the temperature will rise, and when the frequency reaches a certain level, it will melt the iron core and burn down the equipment. Cause disaster. That's why the power transformers in our TV are always hot.
The main function of the transformer core is to guide the magnetic field, so that the electromagnetic field closed loop.
