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.
Unlike capacitors which store energy in an electric field between two conductive plates, or batteries which store energy chemically, an inductor converts electrical energy into magnetic potential energy. When current flows through its coil, it generates a magnetic field in the surrounding space and, often, within a ferromagnetic core.
To convert voltages efficiently, the buck converter needs a mechanism to store the energy while converting it from a higher voltage to a lower voltage. This function is performed by the inductor.
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.
Energy Stored in an Inductor Key Takeaways Understanding the energy stored in an inductor is crucial for various electrical and electronic applications, including power supplies, transformers, and energy storage systems. Inductors play a vital role in regulating current flow, filtering signals, and managing energy transfer in circuits.
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).
