Research on Influence of DC Magnetic Bias on a Converter Transformer

摘要

On the basis of study DC magnetic bias, using 2- dimension transient field-circuit directly coupled finite element method, in virtue of finite element analysis software ANSOFT, quantitatively analyze the influence of DC magnetic bias on excitation current of a converter transformer; On the basis of core loss data, quantitatively analyze the influence of DC magnetic bias on core loss of the converter transformer.
