TDFS Part 3 – Impedance Measurement for Switching Converters and Power System Stability Analysis

Featured Article - Submitted by Mike Donnelly on Tue, 02/21/2017 - 20:55

In this final installment of my series on TDFS (Time Domain Frequency Sweep) analysis, I’ll focus on measuring impedance vs. frequency. I’ll first demonstrate the method by showing the measurement of input impedance for a switching power converter. Then I’ll extend that method to analyze the “impedance stability” of a distributed power system. Power systems may include many DC to DC converters, some acting as sources and other as loads.
