摘要：

A semi-analytical model for calculation of self-inductance of complex coil geometries having a rectangular cross-section (form-wound coils) is proposed and evaluated. A step-by-step validation is carried on using both 2D-FEM simulations and measurements on a coil placed in air. A second version of the model is developed, to speed up the computation time through removing the possibility to analyze the contribution of the internal flux in the conductor. The predicted value of the self-inductance of a diamond-shaped coil placed in air is within 5% of the measured value.
