AC winding loss的用法和样例：
- A three phase symmetry AC winding is used as control winding of the inner stator, a car including ring-like PM rotor as correcting weight.
- Moreover, a new analytical model for the transformer winding loss in flyback converter is also proposed by utilizing the orthogonality of the two field components.
- Then, the thickness of copper foil and strand diameter of Litz wire is discussed to obtain the minimum winding losses.
- Meanwhile the principle is analyzed by using interleaving techniques to decrease winding losses in transformer.
