Stabilization and Output Waveform Improvement of Three-phase Nonlinear Power Device by Saturation Characteristic Relaxation

摘要

This paper clarifies the relationship between theoperation characteristic and the nonlinearity of magnetizationcurves of a nonlinear reactor in an electric power device usingexperimental and numerical analysis. We proposed a newmethod of relaxing nonlinearity of the magnetization curves of anonlinear reactor by the core structure and performed anexperiment in which the method was applied to an actualelectric power device. The result of this research shows that themethod is effective for stabilization of the device and decreasingthe distortion of the output waveform.
