Calculating Inductance Values at Different Currents (or frequencies)
- Simulation Parameters
- In this case, we calculate leakage inductance by applying zero voltage to the secondary winding.
- Varying currents (0.5 to 10 amperes) were applied to the primary side.
- Problem solved at 100 kHz.
- Inductance Calculation
- Inductance is calculated using two methods: circuits and energy.
- The circuits method involves dividing complex voltage by complex current.
- The energy method involves integrating magnetic fields and dividing by the square of the primary current.
- Analysis of Results
- In the current range tested (0.5 to 10 amperes), inductance does not show dependence on current.
- Magnetic flux amplitude in the core remains below the saturation point due to leakage inductance.
