The second edition of the book contains two main additions. The first addition deals with the three-phase pulse width modulation and it is presented in the newly added Section 3.3 of Part III. The second addition is the new Part IV: Advanced Topics. This part deals with analytical solutions of eddy current problems in magnetically nonlinear conducting media in the cases of circular, elliptical and linear polarizations of magnetic fields. This part also contains a section on promising use of spintronics in power electronics.
