6 FAQs about The phenomenon of energy storage inductance size

How does Linear Technology affect inductor energy storage?

While one inductor's current is increasing, the other's is decreasing. There is also a significant reduction in the required inductor energy storage (approximately 75%). The inductor's volume, and therefore cost, are reduced as well. See Linear Technology's Application Note 77 for complete details.

How do inductor ripples affect energy consumption?

The output ripple is reduced in a similar fashion. While one inductor's current is increasing, the other's is decreasing. There is also a significant reduction in the required inductor energy storage (approximately 75%). The inductor's volume, and therefore cost, are reduced as well.

What is inductance in physics?

The concept of inductance condenses all the complexity of a non-linear magnetic field into a single number. It expresses the geometry of the object causing the field - a wire, or a coil, or a toroid - and also the magnetic properties of the material in the object.

Why do buck regulators use double duty energy storage inductors?

The energy storage inductor in a buck regulator functions as both an energy conversion element and as an output ripple filter. This double duty often saves the cost of an additional output filter, but it complicates the process of finding a good compromise for the value of the inductor.

What is the difference between inductance and inductor?

Inductance is the property of a component that specifies how big a magnetic field it can generate when a given current flows though it. An inductor is a component whose designer has tried hard to maximise this property. It's real, like resistance and capacitance, and it can be measured.

Why is a small inductor connected in series with an output diode?

Here, a small inductor is connected in series with output diode DO in order to subside current peaks as the switch is turned on. In addition, the switch dominates power loss in these converters, and the second major is the entire power loss caused due to the three diodes.
