Opto-Isolator Based Linearization Solution for a Thyristor-Driven Pump

Abstract: A thyristor driven pump is operated by varying the DC input signal in the firing circuit of thyristor drive. This operation suffers from difficulties due to the nonlinear relation between thyristor output and DC input. In the present paper, an opto-isolator based linearization technique of a typical thyristor driven pump has been proposed.   The […]

Q&A with Authors of ISA Book Industrial Data Communications

Q. Why did you feel it was important to introduce/write a new edition? A. (Thompson) Data communications is not a static or necessarily “mature” technology. New concepts, applications, and data rates are continually changing. While at a somewhat slower rate, those that improve process communications filter into the industrial areas. A text must be updated, […]
