现有的模拟器中的磁性元件的模型不能以物理上正确的方式描述磁性元件。磁阻模型包括几何信息，并给出准确的结果的能量。电磁电路接口推导出，允许直接列入磁阻模型的模拟。利用分布磁阻模型精确地描述了磁体中的能量。采用有限元分析方法求取模型参数。该方法可以在任何电路仿真程序中实现。给出了SPICE模拟器的实例。<<ETX>>
Existing models of magnetic components in simulators fail to describe magnetic components in a physically correct manner. The reluctance model includes geometric information and gives accurate results for the energy. An electric-to-magnetic circuit interface is derived that allows the direct inclusion of the reluctance model in the simulation. The energy in the magnetics is accurately described by use of the distributed reluctance model. Finite-element analysis is used to obtain the model parameters. The approach can be implemented in any circuit simulation program. Examples for the SPICE simulator are given.<<ETX>>
