Power-supply failure takes on significant importance in high-end computer, telecom, medical, and industrial applications, in which uninterruptible power is paramount. In these systems, diode-OR-ed ...

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 ...

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 ...

At one time, the National Electrical Code (NEC) contained two Articles you won’t find as of the 2020 revision: Art. 280 (surge arrestors) and Art. 285 (transient voltage surge suppressors or TVSS).

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 ...

Careful design limits overvoltage on the supply input of integrated circuits, and avoids compromising an IC's specifications. Overvoltage damage can cause an immediate failure, or accelerate an ...

Authorities had scrambled to find answers after the April 28 outage Spain and Portugal were hit by widespread power blackouts in April. Officials revealed Tuesday (June 17) that it was caused by ...

A widespread blackout plunged Spain and Portugal into darkness and has been identified as “one of its kind.” The official report of the European Network of Transmission System Operators for ...
