Finding a 480V-ac solid-state timer having zero-crossover switching may prove to be an impossible task. Most solid-state timers are rated at only 1A and have voltage ratings no higher than 240V ac.

Protective relay testing verifies that installed relays will trip correctly under real fault conditions, confirming settings, ...

Abstract: This paper presents the design and implementation of a novel matrix-friendly genetic algorithm (MGA) based population input memristor circuit. Selection, crossover and mutation operations ...

Abstract: In this paper, a 0.18-V input three-stage charge pump circuit applying forward body bias is proposed. In the developed charge pump, all the MOSFETs are forward body biased by using the inter ...

This month’s Friday Five explores decisions reviewing what evidence is necessary to prove that a condition like long COVID is ...

An AC resonant test system is designed to generate high alternating voltage by forming a resonant circuit between the reactor and the test object. By operating at or near resonance, the system can ...

AI smart speakers and AI-enabled home automation devices are widely adopted and continue to see strong demand. However, achieving seamless integration with a ...

Two tuners were developed for this receiver. The more sensitive one uses tetrode transistors in the RF amplifier, mixer and oscillator. Its disadvantages lie in a much higher cost and a 12 to 14 db ...

Delaware hosts the Florida International Panthers after Safiatu Kolliegbo scored 20 points in Delaware's 79-54 loss to the Missouri State Bears. Sunday's matchup is the first of the season between ...
