A personal computer (PC) sound card can be the basis for a readily available signal generator for testing electronic circuits. The usefulness of these signal generators is limited, however, because ...

This article describes a simple technique for using a processors PWM output to produce an analog control voltage that matches the load’s input range, thus maximizing control resolution. Most ...

Pulse-width modulation (PWM) is an efficient method for controlling the light intensity of a lamp or the speed of a simple DC motor. It lets you take advantage of the load's inertia by switching the ...

When multiple PWM converters are connected in series (or in parallel) in a power electronics circuit, it is appropriate to run all converters at the same frequency but with certain phase shift among ...
