Information

This model compares a transient-linear magnetic circuit with a quasi-static magnetic circuit. A sinusoidal voltage is applied to an inductor with a closed ferromagnetic core of rectangular shape.

Compare the following quantities

  • Sinusoidal supply voltage
    source.v | sourceQS.v.re|im
  • Non-linear transient current due to saturation and equivalent quasi-static current
    currentSensor.i | currentSensorQS.i.re|im
  • Difference between RMS fundamental wave of transient current and the RMS quasi-static current
    feedback.y
  • Relative permeability of iron core of transient and quasi-static circuit
    r_mFe.mu_rConst | r_mFeQS.mu_rConst
