Testing a power supply at different load currents and different input voltages is important, but it only shows part of the ...

Network analysis is a powerful and well-established method of characterizing and optimizing a control system. [1] Unfortunately, making a successful measurement can be difficult and frustrating ...

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 ...

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 ...

I'm frequently asked why I refer to the effective inductance of a voltage reference, voltage regulator, or op-amp in my articles. Others question “Is there really an inductor in there?”, “Where does ...

Plant engineers and technicians are frequently asked to tune the controller when a control loop’s process value has prolonged or significant excursions from the set point. But in many instances, no ...
