6 FAQs about [Buck s energy storage inductor]
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.
How much energy does a buck boost inductor handle?
A Buck-Boost inductor has to handle all the energy coming toward it — 50 μJ as per Figure 5.4, corresponding to 50 W at a switching frequency of 1 MHz. Note: To be more precise for the general case of η≤1: the power converter has to handle P IN /f if we use the conservative model in Figure 5.1, but only P O /f if we use the optimistic model.
How do you choose a buck converter inductor?
Key considerations in inductor selection include: Inductance—the rated value of the inductor and its impact on the ripple current in the buck converter. DC current rating—translated from the output current needs of the buck converter, the DC current rating is linked directly to the temperature rise of the inductor and its DC resistance (DCR).
What is a buck boost inverter?
