Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
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
