In-circuit Measurement of Inductors and Transformers with an Oscilloscope

In-circuit Measurements of Inductors and Transformers App Note

An oscilloscope can be used to measure the performance of inductors and transformers under operating conditions.  This application note:

  • Provides a quick review of practical inductor and transformer theory, especially related to power supply designs
  • Explains how to use an oscilloscope, equipped with power analysis software to measure performance under operating conditions
  • Explains the use of dynamic inductance measurements and B-H curves to gain insight into performance
