Compare Soft Saturation vs. Regular Inductor - Switching LuisJoseDesigner21526 × LuisJose Member for 8 years 2 months 1 designs 1 groups Add a bio to your profile to share information about yourself with other SystemVision users. https://explore.partquest.com/node/42256 <iframe allowfullscreen="true" referrerpolicy="origin-when-cross-origin" frameborder="0" width="100%" height="720" scrolling="no" src="https://explore.partquest.com/node/42256"></iframe> Title Description <p>This design shows the importance of choosing the right inductor size and type, to avoid saturation-induced current spikes during operating transients. In this case, the start-up transient in two nearly identical open-loop buck power stages (12V -> 3V) is examined. The only difference is that the top circuit is using an inductor calibrated to a Coilcraft XAL6060-223 (22uH), which has "soft saturation" behavior. The bottom circuit is using a similarly sized inductor, but with a more typical "hard saturation" characteristic. </p><p>Both inductors work well for the steady-state load condition of 3 Amp. But during the turn-on transient, that current can go significantly above that nominal level. At that time, the instantaneous inductance of the hard-saturating device collapses, resulting in even larger current spikes in each switching interval. Note in the waveforms on the left: The soft-saturation inductance drops to 14uH minimum during the transient, whereas the hard-saturation inductance crashes to near 2uH, or only 10% of its nominal value!</p> About text formats Tags Buck Power Stageinductance collapseCoilcraftXAL6060-223 Select a tag from the list or create your own.Drag to re-order taxonomy terms.
