Compare Hard Saturation Inductor (modeled with a magnetic equivalent circuit) to XAL8080-103 Designer https://explore.partquest.com/node/602331 <iframe allowfullscreen="true" referrerpolicy="origin-when-cross-origin" frameborder="0" width="100%" height="720" scrolling="no" src="https://explore.partquest.com/node/602331"></iframe> Title Description <p>This example shows that you can build a hard-saturation inductor model from magnetic components (i.e. a winding, a non-linear and lossy core, as well as an air-gap if needed). In this test circuit, the performance of that magnetic equivalent circuit, parameterized to represent a 10uH inductor, is compared to the soft-saturation behavior of a Coilcraft XAL8080-103.</p> <p>Note: If you increase the applied voltage pulse to 20V, the results will show the comparatively favorable performance of the XAL8080-103.</p> About text formats Tags magnetic coremagnetic saturationmagneticsAir Gap Select a tag from the list or create your own.Drag to re-order taxonomy terms.

Measure magnetic path reluctance Designer https://explore.partquest.com/node/481817 <iframe allowfullscreen="true" referrerpolicy="origin-when-cross-origin" frameborder="0" width="100%" height="720" scrolling="no" src="https://explore.partquest.com/node/481817"></iframe> Title Description <p>Using a ramped current source with di/dt = 1, and since v = L*di/dt, the inductance is equal to the voltage seen across the winding. In both these cases, the value if inductance = voltage = 1mH.</p> <p>We know from electro-magnetic circuit theory that the inductance is equal to n^2/Reluctance. Therefore, in the top circuit, the unknown reluctance can be computed as 1m = 96^2/Reluctance, or Reluctance = 9.216megA/Wb.</p> <p>This calculation is confirmed by comparison with the bottom circuit, where that reluctance value is directly applied to a simple magnetic reluctance model. Note that the winding terminal voltage is almost identical to that of the upper circuit.</p> About text formats Tags magnetic coremagnetic saturationmagneticsAir Gap Select a tag from the list or create your own.Drag to re-order taxonomy terms.
