The magnetic modulation of DC transformer core characteristics analysis

For the core characteristics of Magnetic Modulation DC transformer, This paper established the Magnetic Modulation DC transformer model based on ANSYS and carried out the three-dimensional finite element simulation for the core. The simulation data show that if we select the appropriate parameters and adopt the theoretical analysis, we can know the measured DC current and the average permeability showed a nearly linear relationship. The results show that the method is useful for engineers to understand better of magnetic field in a modulation direct current sensor and help for more accurate basis for designers.
