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 ...

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, ...

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 ...
