IN their communication under the above heading, Messrs. Le Brocq and Cocks 1 redirect attention to a point that has been too often overlooked: namely, that the effectiveness of a metal as the cathode ...

In industrial applications using digital-to-analog converters (DACs), programmable logic controllers (PLCs) set an analog output voltage to control actuators, motors, and valves. PLCs can also ...

CONSIDERABLE confusion has been caused in the past by neglect of the influence of the hydrogen overvoltage on the corrosion current between metallic couples in electrolytes.

The good thing about being a field applications engineer is that you get to work on many different circuits, often all at the same time. While this is interesting, it also presents problems. Jumping ...

Researchers from King Mongkut’s University of Technology North Bangkok in Thailand have proposed a new methodology to conduct techno-economic assessments of distributed PV systems considering ...

High demands on the robustness of electronic systems, especially in industrial environments, continually present developers with great challenges. Overvoltage protection is one key design ...

A major power outage in April was caused by grid overvoltage, triggering a chain reaction. The Spanish grid lacked sufficient voltage control capacity, contributing to the blackout. Minister Aagesen ...

To ensure reliability and safety for devices that run on ac and dc power lines, circuit protection is a definite design requirement. Unfortunately, there’s no universal protection solution. Varying ...

Australian scientists have identified seven methods to prevent PV losses when overvoltage-induced inverter disconnections occur. The methods include battery storage, reactive power inverters, export ...

This circuit provides undervoltage and overvoltage protection for dc input supply voltages (see the figure). Its undervoltage cutoff is 6 V, and its overvoltage cutoff is 11.5 V. D3 is included for ...
