Variable capacitors may be useful, but the air gap that provides their capacitance is their greatest weakness. Rather than deal with the poor dielectric properties of air, some high-end variable ...

A voltage multiplier is applied as a high source impedance, 36V, 300mA, 12W LED driver. The high source impedance is ideal for driving power LEDs because it accommodates variations in LED junction ...

Find a downloadable version of this story in pdf format at the end of the story. In any industry, there are applications whose failure could mean lost revenue and increased annoyance. In very few ...

Capacitive sensors supply high accuracy at a relatively low cost. But system designers attempting to use them have been forced to first convert the capacitance to a voltage, then convert the voltage ...

Back in 1971, Leon Chua, a young electronics engineer at the University of California, Berkeley, began working on a fundamental mathematical framework for electronics. His theory was based on the ...

Southern States CapSwitcher is a high-voltage capacitor switching device specifically designed to meet the power quality needs of today's electrical systems. This special purpose SF6 capacitor switch ...
