绕组尺寸和位置的差异决定了漏磁路径，并引起短路阻抗的不平衡，这强烈影响了Transformer的暂态行为。这项工作提出了一种新的建模方法与磁等效电路，利用Transformer的几何形状和磁导等效电路，这是适合系统级仿真的复杂性。等效模型需要有限数量的参数和验证的目的，有限元模拟以及测量的实验原型已经执行。
The size and position difference of the windings determine the leakage flux path and give rise to unbalance of the short-circuit impedances, which strongly affects the transient behaviour of the transformer. This work proposes a new approach of modelling with magnetic equivalent circuit, making use of the transformer geometry and permeance magnetic equivalent circuit, which is suitable for system-level simulation in terms of complexity. Equivalent model requires limited number of parameters and for verification purposes, FEM simulations as well as measurement on the experimental prototype have been performed.
