在对磁性元件建模时，磁导电容类比避免了传统等效电路模型的缺点。磁路结构很容易从磁芯的几何形状推导出来，并且保持了电畴和磁畴之间的能量关系。非线性磁芯材料可以用可变磁导进行建模，从而实现任意饱和和磁滞功能。频率相关损耗可以通过磁路中的电阻实现。磁畴已在仿真软件PLECS中实现。为了避免数值积分误差，在求解电路方程时，必须将基尔霍夫电流定律应用于磁通量和磁通率。
When modeling magnetic components, the permeance-capacitance analogy avoids the drawbacks of traditional equivalent circuits models. The magnetic circuit structure is easily derived from the core geometry, and the energy relationship between electrical and magnetic domain is preserved. Non-linear core materials can be modeled with variable permeances, enabling the implementation of arbitrary saturation and hysteresis functions. Frequency-dependent losses can be realized with resistors in the magnetic circuit. The magnetic domain has been implemented in the simulation software PLECS. To avoid numerical integration errors, Kirchhoff's current law must be applied to both the magnetic flux and the flux-rate when solving the circuit equations.
