After designing a control loop within a power supply, motor drive, or almost any power-electronics product, engineers must establish that they have achieved their target specifications for loop ...

These three analysis methods are linked together, so this section is organized by control method. In contrast to the large-signal transient response that was reviewed in part 2, we will perform ac ...

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. It will explain the ...

PID (proportional, integral, derivative) control has existed for decades and there are many tools available to help implement PID to tune process control systems, thereby making it generally easy to ...

The days when converter manufacturers would have little option but to rely on the expertise of power-module specialists to design filters, optimize the control loop, and provide the result, have given ...

Learning the basics can ease loop tuning frustration and ensure stability. During plant operations, it seems that tuning control loops is an ongoing task, which can be a continual frustration to ...
