Low-voltage arc sustainability

2017 IEEE IAS Electrical Safety Workshop (ESW), 2017
Arc Flash in low voltage equipment (480 volts and below) is a safety issue that can impact work practices for electrical workers. When estimating incident energy for low voltage equipment, the duration of the arc is typically the driving factor. This paper summarizes previous testing results that establish arc sustainability for various equipment ...

A New Switched Capacitor 7L Inverter With Triple Voltage Gain and Low Voltage Stress

IEEE Transactions on Circuits and Systems - II - Express Briefs, 2020
In this brief, a new switched capacitor based multilevel inverter topology is proposed. The proposed topology generates seven level (7L) output voltage using a single dc voltage source along with two floating capacitors.

Low-Voltage Fluorescent Lamps

Transactions of the American Institute of Electrical Engineers, 1938
FLUORESCENT lamps have been developed, simple in design, and operating through suitable ballast from 115- and 230-volt a-c circuits. They are tubular in form, and the fluorescent material is energized by a hot-cathode positive-column electric discharge.

Low-voltage CMOS voltage squarer

2009 16th IEEE International Conference on Electronics, Circuits and Systems - (ICECS 2009), 2009
A voltage squarer based on bulk-driven PMOS transistors is proposed in this paper. Circuit topology employs a voltage attenuator and the quadratic I D /V G characteristic of a MOS in saturation. The squarer was designed with a 0.8V supply voltage using standard 0.35um CMOS process, which offers large value of threshold voltage.

Low voltage EELS—How low?

Ultramicroscopy, 2014
Using low beam energies in a (scanning) transmission electron microscope (S/TEM) has numerous advantages over higher beam energies. We discuss the performance of commonly available electron microscopes when being operated at reduced beam energies.
