The hobby circuit below uses an unusual method to generate about 12,000 volts with about 5uA of current. Two SCRs form two pulse generator circuits. The two SCRs discharge a 0.047uF a 400v capacitor ...

[The LED Artist] often found a need for a relatively high voltage (100 to 200 Volt) but low current DC power supply, and it turns out that a small HV generator that uses a single AA cell only took ...

Here’s a project that could be useful this summer on the beach, to stop anyone touching your things left on your beach towel while you’ve gone swimming; you might equally well use it at the office or ...

In this article, I'll show you how to build a simplistic circuit to generate negative ions. Negative ions have been known to contribute to fresher air, happier mood, and general health benefits.

NEMA, Rossyln, Va., has published SG 4-2009, "Alternating Current High-Voltage Circuit Breakers." The standard, which NEMA published under license from IEEE, Piscataway, N.J., was revised by the ...

ABB has released the Switching Control Sentinel (SCS) device designed for high-voltage circuit breakers. Voltage and current transients generated during switching of high-voltage circuit breakers are ...
