Performing In-Circuit Inductor and Transformer Measurements in SMPS (.PDF Download)

In switched-mode power supplies (SMPS), magnetic components, namely inductors and transformers, play critical roles. Much of the SMPS design process relies on component specifications and simulation models. However, due to actual signal conditions, parasitics, temperature, and other environmental factors affecting magnetic components’ performance, a power supply may not perform exactly as predicted by specs and simulations. As a result, in-circuit measurements of inductors and
