eGuide: Practical tips for accurate Bode plot measurements
May 18, 2020
This online guide includes a wealth of practical tips for choosing suitable equipment, setting up measurements, running tests, and interpreting the measurement results.
To investigate the stability of a switched-mode power supply, a Bode plot created with an oscilloscope is ideal for checking the critical phase margin and gain margin values. The factors that determine how satisfactory the results from Bode plot measurements will be, need to taken into consideration as part of the preparation.
Stricter guidelines imposed by version 3 of the IEC standard for harmonic current emissions push designers to embrace power-factor-correction methodologies.
The flyback topology is a versatile, widely used, switched-mode power-supply design with some interesting characteristics that brings performance and BOM advantages to many applications...
Power supplies are everywhere and there are a lot of options for designers. Knowing the differences can help in selecting one for a particular application.
