6 FAQs about [Energy storage inductor wire diameter requirements]
Why is wire size important in inductor design?
Wire size is an important aspect of the inductor design since a given wire can handle only a limited current density to avoid excessive power loss. The wire-winding window of a given core must have enough area so that copper wire of a given diameter can be used and all the required number of turns fit.
How to choose a power inductor?
on among users.DC resistanceOnce the required values for inductance L and inductor currents are calculated, you select a power inductor with the m nimum possible DC resistance. Here the de ands are often counteractive:Small size, high energy storage
What is a small DC inductor?
A small DC inductor is typically limited more by the core’s available window area than its cross-section area. The core’s window must be large enough to accommodate the number of turns of wire required to reach the specified inductance. A large DC inductor is often limited by the core’s saturation point.
What are the requirements for inductance rating?
Requirements: Inductance rating L N = 100 µH Current rating (DC) I N = 1 A Peak current through the inductance I max = 1.5 A Ripple current = 20% of I max = 0.3 A (see Chapter III/Applications) Switching frequency f = 52 kHz
How to choose the smallest inductor for a switching regulator?
These core selection procedures simplify the design of inductors for switching regulator appli-cations. One can determine the smallest core size, as-suming a maximum decrease in inductance of 50% and wire current carrying capacity of 500 circular mils per ampere. DC current.
How to calculate current load for power inductors?
or.Inductor current ratingsThe current load for power inductors can be calculated very accurately in terms of DC current load and ripple current load (core losses) using the manufac urers’ simulation software. The following approach can be I = 2 x Imax NDESIGN TIP 3:Please observe the definitions for
