Abstract
To solve the problem of the existing methods which can only draw the total magnetic flux distribution, a new method for studying the harmonics of the magnetic flux distribution based on harmonic-balance finite element is proposed in this chapter. Firstly the theory of the harmonic-balance finite element method is introduced in this chapter. Secondly, a new type of converter transformer coupled with field–circuit mathematical model is established, and the corresponding 2D axis symmetric finite element model is provided. On that basis, the distribution of harmonic flux is obtained by writing programs using MATLAB software, with a deep analysis included. This method is an innovative approach and also makes up the shortcomings that finite element software cannot get the distribution of each harmonic magnetic flux which has important meanings in the design of the transformer and other electromagnetic equipments.
