Typical circuits textbooks tell us that there are four basic feedback topologies. The impression is given (if not stated) that a given feedback circuit will conform to one of these four topologies.

In some power-supply applications, the pulse-width-modulator (PWM) controller is powered up from an auxiliary winding tapped off the power stages transformer (Fig. 1). This technique reduces power ...

Piezoelectric shunt damping is an innovative method for mitigating unwanted vibrations in structures by exploiting the electromechanical properties of piezoelectric transducers. When bonded to a ...

Q: What are the circuit connections that you use for elevator recall and elevator shut-down (shunt trip)? A: Continuing from last month's discussion, it is hard to avoid the same lengthy/wordy ...
