How to Choose Power Inductors in Boost and Buck Converter Circuits?
Choosing the right power inductors for boost and buck converter circuits is crucial for their proper operation. Here are some guidelines to help you make the right selection:
>In a non-isolated power supply circuit, a boost converter typically consists of three primary components: L (inductor), SW (switching element), and D (diode), in addition to input and output voltage stabilizing capacitors. When selecting an inductor for the boost converter, it's generally advisable to choose one with higher inductance capable of handling lower currents. Commonly used products in this category include plug-in types like the RCB, RDR, and TC series. If you prefer surface-mount components (SMD), you can consider the SDS, SQH, or SEP series.
When it comes to selecting an inductor for a buck converter circuit, you typically opt for an inductor with lower inductance that can handle higher currents. Commonly used products in this category include plug-in types like the REP and TC series. For SMD components, you can explore options like SBP, SEP(A) flat wire, or SEP/SER series.
Please keep in mind that the choice of inductor is also influenced by the specific requirements and constraints of your application. Therefore, in practical design, further assessment and optimization of the inductor selection may be necessary.
