Abstract: Aimed at the distortion of ferro magnetic material hysteresis loop under direct current magnetic bias, this paper used the back propagation neural network theory to realize matching of hysteresis loop based on magnetic controlled reactor on the platform of Matlab, simulating the winding current distortion under direct current magnetic bias. The results show that the matching hysteresis loop is close to the practical measured curve. The excitation current changes are consistent with theoretical analysis, which provides an effective approach for the research of hysteresis loop matching and current distortion under direct current magnetic bias.
Key words: hysteresis loop; direct current magnetic bias; back propagation neural network; magnetic controlled reactor; current distortion
