Both core and wire winding losses as well as saturation effects establish design rules for those who “wind their own inductors” as shown below. Limitations of magnetic cores are crucial to good inductor design 1. Core Material Limitations:In dc applications, inductors are primarily thought of as current operated devices.
If an inductor carries a constant dc current below its saturation limit, the core flux will be constant, and the hysteresis and eddy current losses of the core will be zero. In practice any switch mode converter has large current ripple in the inductors, at the switching frequency. The flux variation will be follow the AC current.
In switching regulator applications the inductor is used as an energy storage device providing the ability for power and voltage conversion within a circuit. The basic converter topol-ogies for switching regulator inductors are Buck (step-down), Boost (step-up), Buck-Boost (step-down/up) Cuk (step-up/ down) and SEPIC (Step-down/up).
the inductance in Henrys and I is the peak value of inductor cur-rent. The amount by which the current changes during a switching cycle is known as the ripple current and is calculated by the formula; = L x di/dt is the voltage across the inductor, di is the ripple current, and dt the duration that the voltage is applied.
The inductor must be able to handle the peak switching current without saturating the core, which would result in a loss of inductance. At the expense of higher output-voltage ripple, small-value inductors result in a higher output-current slew rate, improving the load transient response of the converter.
Shielded inductors in ferrite material are small and don’t radiate much energy. Choosing an inductor often depends on the price/size tradeoffs, and on requirements for radiated-field/electromagnetic-interference suppression. Figure 5.
