Application of saturated inductor in switching power supply
1) Since the saturation magnetic field strength is very small, the energy storage capacity of the saturable inductor is very weak and cannot be used as an energy storage inductor. The theoretical value of the maximum energy storage Em of the saturable inductor can be expressed by equation (1).
HOME APPLICATION NOTES
Energy storage inductor designs will be limited by either magnetic saturation or excessive temperature rise resulting from both winding and core losses. In the case of iron powder, due to the fairly low permeability, moderate core loss properties, and very gradual

The discrete gap structure results in an inductor that reaches a sharp saturation point, requiring lots of headroom in the design. ... The inductor designer must meet the energy storage (inductance) requirement, as well as requirements for total loss, space, cost ...
Energy stored in a saturating inductor
We have a core of some nominal energy storage capacity, independent of the winding we put around it; the question, then, is what impedance -- what ratio of voltage to current -- the circuit needs. The turns count is the transformer matching ratio for …
Permanent Magnet Hybrid Core Inductors for High Saturation …
Inductor designs with large dc current relative to ac ripple are often saturation-limited, but these designs also often greatly underutilize the core material''s flux carrying capabilities. Instead of using the full flux swing range from reverse saturation to forward saturation, these designs typically only use half the range. To use the full range, we propose a …
Modeling Inductors with LTspice
When this happens, inductors are not able to continue storing energy. This situation is reversed as soon as the current circulating through the inductor is reduced. This concept of saturation must be considered in models in order to have accurate simulations for applications such as power supplies, where magnetic components are …

In addition, saturation is the point when an inductor can no longer store energy and instead shows a drop in energy storage and inductance. From the inductor current waveform, in figure 1, it is evident …
Inductor Saturation Current and Temperature Rise Current
1) The saturation current value (Idc1) is the DC current having inductance decrease down to 30% (at 20 dec C). If you exceed this, the inductor will saturate and the current will rise sharply. You want to avoid this or your …

Controlling and Preventing Core Saturation in Inductors
Core saturation is one of the main limitations on the design of magnetic components. In this article, we explore how different factors—particularly the number of turns—impact the core saturation of an inductor. In the previous article, we saw that a strong magnetic field can cause saturation in magnetic materials. ...
