Most of us know about PWM DACs. They are easy to implement, cheap, and acceptable for low performance applications. The approach is to filter the HF components of the PWM signal and be left with only ...

Many applications using miniature brushed DC motors require motors to operate at more than one load point or through specific load cycles. Running a motor at usable load points requires a variable, ...

The trend is clear: The Power Supply industry is starting to accept full-digital control of Switch Mode Power Supplies (SMPS) as a viable control technology. The advantages this trend brings are ...

I have been discussing control algorithms for a power supply and idly looking for some easy hardware on which to try the technique – hardware small enough to build into a prototype. See also: An AVR ...

This file type includes high resolution graphics and schematics. You can build an analog calculator using a pulse-width modulator (PWM) to perform accurate four-quadrant multiplication and division.
