The Rohde & Schwarz application note describes how to measure the control loop stability of switch-mode power supplies to get the best performance and confidence of the design.

This white paper describes how to measure the control loop stability of switch-mode power supplies to get the best performance and confidence of the design.

It will explain the main measurement concept and will guide the user during the measurements and mention the main topics in a practical manner. Wherever possible, a hint is given where the user should pay attention to it to avoid weak measurements. The Rohde & Schwarz buck converter reference board was designed in collaboration with Texas Instruments and is used to illustrate the closed loop measurement in a practical manner.

Key Learning Points:

  • Tips and tricks on how to verify control loop stability
  • More about oscilloscopes and how to get the tasks done
  • How to use Rohde & Schwarz probes to get the tasks done
This free white paper resource is available to IET members and non-members.
