Power supplies use control-loop circuits to produce constant voltage or current. The transfer function—gain and phase as a function of frequency—provides valuable information about a control loop’s ...

While process manufacturers have justified nearly 30 years of automation investments on the observations of one man, today’s control loop performance monitoring technologies are providing new, ...

Power plants–especially coal-fired boilers–pose a set of process control problems unparalleled in other industries. Rapid load ramps, continuous unit demand changes, variable fuel quality and process ...

At the core of any modern industrial process is a control system guaranteeing precision, stability, and efficiency. Perhaps the most commonly used are PID (Proportional-Integral-Derivative) ...

Application flexibility and cost concerns are creating a demand for intelligent power-supply designs that support soft configuration in production and external control. These advanced power supplies ...

Thermoelectric coolers (TECs) based on the Peltier effect can be used for general cooling, but more often they’re applied to maintain a precise temperature for subsystems and components. And unlike ...
