6 FAQs about [Q value of energy storage inductor]

What is the Q value of an inductor?

The Q value of an inductor is a measure of the relative losses in an inductor. The Q is also known as the “quality factor” and is technically defined as the ratio of inductive reactance to effective resistance, and is represented by: L L frequency at a faster rate than Re at lower frequencies, and vice versa at higher frequencies.

What is Q factor in inductor?

In the context of inductors, the Q factor represents the efficiency of energy storage and release in the magnetic field, as well as the energy loss in the form of heat due to the coil’s resistance. The Q factor of an inductor is defined as the ratio of its inductive reactance (XL) to its series resistance (R) at a specific frequency:

What is the Q of an inductor with a series loss resistance?

The Q of an inductor with a series loss resistance is the Q of a resonant circuit using that inductor (including its series loss) and a perfect capacitor. where: RL is the series resistance of the inductor.

What affects the Q factor of air-core inductors?

Core material: The choice of core material affects the Q factor, as different materials have different magnetic properties and loss characteristics. Air-core inductors typically have a higher Q factor than those with magnetic cores, as magnetic materials can introduce additional losses.

How does permeability affect inductor Q?

on a given design, as inductance (turns of wire) goes up, the Q goes down. If the permeability of the core is increased, the number of windings can be reduced and incremental current may increase or decrease.* higher Q generally indicates an inductor that is a more selective filter.

Why is a small value inductor important?

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.
