All power supplies require some type of feedback loop to regulate the output voltage. A simplified diagram of a buck controller is shown in Figure 1 with a pulse ...

Every plant in the process industry most likely has several control loops that do not perform well. Although there are many factors that may negatively affect control loop performance, a few of these ...

Editor’s note: There is a great deal written about isolation, but Frederik Dostal gives us a look at power supply isolation. Do you know which side of the galvanic isolation to put the controller?

Manufacturers today face many hurdles in their manufacturing applications. Process parameters can range from one application to the next. While some applications require very little precision and ...

Switching power supplies rely on feedback control loops to ensure that the required voltage and current are maintained under varying load conditions. Design of the feedback control loop influences ...
