Explore the concept of negative feedback and its role in maintaining system stability across various applications.

Closed-loop flyback converter block diagram. Before making the necessary calculations for the controller to stabilize the peak current control mode flyback, it’s important to understand the components ...

The magnetic components, switches, and output capacitors affect the control-to-output gain as a function of frequency. The feedback control has its own challenges, and the parasitic elements in the ...

Self-regulating systems with feedback loops, i.e., the routing back of the output of a system to its input, have existed since antiquity and have since become an integral part of modern technology.

For most closed-loop feedback control systems, phase margin is greater than 45° (less than 315°) when the loop gain is greater than 0 dB. Gain margin is -20 dB or lower when the loop phase delay ...

By Jim Ford, PhD. Just over a decade ago, an article titled, "Advanced Control Strategies Move into the Field" (Control, October 2008), highlighted three evolving trends in the process control world ...

To implement this control loop, Analog Devices announced the LTM4663, a complete 1.5-A sink/source thermoelectric cooler (TEC) regulator in a 3.5- × 4- × 1.3-mm LGA package (Fig. 1).
