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 ...

If you build electronic circuits on a regular basis the chances are you will have used capacitors many times. They are a standard component along with the resistor whose values are lifted off the ...

My friend's computer has been acting flakey, especially when he's got a lot of bus-powered USB devices plugged in. I've narrowed the problem down to either the motherboard or power supply. The power ...

As you will probably already know if you are engaged in electronics design at some level, a capacitor is a passive device ...

All buck converters need capacitors on the input. Actually, in a perfect world, if the supply had zero output impedance and infinite current capacity and the tracks had zero resistance or inductance, ...

This file type includes high resolution graphics and schematics. Capacitors often are connected in parallel in power electronics to decrease high-frequency ripples, current stress, decrease power ...

Many power supplies use hold-up capacitors to keep enough energy at the full-wave or bridge rectifier output to supply a load when the rectified voltage drops and rises again at the next half-cycle of ...

Editor’s note: The following is Part one of a technical white paper by Ericsson with some very educational and practical design information. The paper discusses the Loop Compensator and Capacitor ...
