Leakage Inductance

Calculating Leakage Inductance for Transformers

  1. Setup
    • Go to the Setup and choose to calculate Inductance under Electromagnetics.
  2. Configuring Elmag
    • Enable the secondary winding.
    • Choose voltage under excitation.
    • Ensure all coil groups are connected to primary or secondary as needed.
  3. Configuring Waveforms
    • Set the voltage on the secondary side to zero to close the circuit.
    • Perform a frequency sweep for a given amplitude of current to calculate leakage inductance.
  4. Results
    • Leakage inductance is calculated using energy and circuits.
  5. Visualization
    • Check the magnetic flux from which leakage inductance was calculated.
    • Adjust the time variable to view magnetic flux at different frequencies.
