| Abstract: | This essay introduces the theoretical analysis and simulation study of the harmonic components of the field current under the condition of the DC magnetic biasing. The research result shows that there is mainly second har- monic in the field current under the condition of the DC magnetic biasing of the converter transformer, there is a lin- ear relation between the second harmonic and the injected DC, and the second harmonic grows faster than other low- order harmonic with the growing DC. |
