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.
What is a buck boost inverter?
Based on buck, boost or buck-boost topologies, which are well known in dc–dc converters, these inverters use dc inductors for energy storage or high-frequency transformers for both energy storage and electrical isolation as required for safety reasons. A buck-boost inverter topology with four power switching devices is shown in Fig. 11.
What is a peak inductor current in a buck regulator?
Peak inductor current in a buck regulator with continuous mode operation is: The core used for L1 must be able to handle 3.93A peak current without saturating. Peak inductor currents in discontinuous mode are much higher than output current: The 10μH inductor, at 1A output current, must be sized to handle 4.14A peak current.
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.
