説明
Mn-Zn ferrite cores are used for DC-DC converters under the excitation conditions of frequencies ranging from tens of kilohertz to several megahertz. The development of a mathematical model enabling the power loss of Mn-Zn ferrites to be estimated in high-frequency regions, should contribute to improving the design of the converters. The spatial network method (SNM) has been used to analyze the electro-magnetic field of electric machines and applied to obtain the power loss in ferrites whose properties have been treated as linear. This paper presents the SNM including ferrite’s non-linear magnetic properties, which are magnetic saturation, hysteresis and dynamic magnetic losses. In addition, the dielectric features of Mn-Zn ferrite are taken into account. The simulated results are closely in accordance with the experimental values and demonstrate dimensional resonance caused by high-frequency excitations.
