Process-Control MethodsProcess-Control Methods
Depending on the controlled variable and how fast or slow it changes, every control system must have a controller that provides a signal to the final control element. Keep in mind that the controller is the decision maker that sends a signal to a final control element based on two things: the desired set-point and […]

What is the importance of using P&ID for process engineering? I currently work at Georgia Pacific in wood products, we make OSB. I have worked as an electrician on shift for several years which meant that there were several times that I would have to troubleshoot and identify issues on my own because […]
Discussion Reply: ThyristorsDiscussion Reply: Thyristors
Thyristors are semiconductors that are, essentially control systems for switching and controlling power. The ones used most are Silicon-Controlled Rectifiers (SCRs), Diode AC Switches (Diacs), Triode AC Switches (Triacs), and Uni-Junction Transistors (UJTs). Here’s a breakdown of each one and how they function: Silicon-Controlled Rectifiers (SCRs): Three-terminal semiconductors used for controlling the flow of […]

What are some of the effects that power quality might play in the selection of different devices? For example, power supplies may be subject to transients, harmonics, variations in voltage and (sometimes) frequency and so forth. Also, what about temperature variations, vibration, dust, and other environmental challenges. How could we go about determining which type […]

Thyristors are semiconductor devices that are used as switches to control higher-level voltages and current. Unlike variable control, thyristors have two states: fully open or fully closed. In your original post, answer the following: Discuss the operation of different thyristors such as SCRs, Diacs, Triacs, UJTs, etc., with an emphasis on the application of […]
