How to calculate leakage inductances?


MANATEE offers several possibilities for the calculation of leakage inductances used in the equivalent circuit:

  • slot leakage inductance
  • skew leakage inductance
  • differential leakage inductance
  • zigzag leakage inductance


Depending on chosen electromagnetic model, leakage inductance can be calculated using analytic model or finite element. To accurately capture non linearities, using the automated coupling with FEMM is advised.
