In the previous article, we talked about the copper loss of the transformer. Now let's talk about the iron loss of the transformer.
The iron loss of the transformer mainly includes two aspects: one is the hysteresis loss, and the other is the eddy current loss;
The hysteresis loss means that when the alternating current passes through the coil, magnetic lines of force will be generated through the iron core, and the molecules inside the iron core will rub against each other to generate heat. This consumes part of the electric energy.
Because the magnetic lines of force pass through the iron core, the iron core will also generate an induced current, which is also called eddy current because the current is eddy current, and the eddy current loss will also consume part of the electric energy.
