Even as electronic components shrink, it is always an easy task to spot the power supply section on small-sized boards given the large amount of space the inductive and capacitive filter components ...

This file type includes high resolution graphics and schematics when applicable. Switch-mode power supplies based on pulse-width modulation (PWM) have been in use since the early 1970s. One of their ...

The PC power supply has been a standard of the junk box for the last couple of decades, and will probably continue to be for the foreseeable future. A product that is often built to a very high ...

A new IC-based approach to EMI filtering in ac-dc power subsystems dramatically cuts inductor size and offers other benefits as well. The nature of the EMI problem in ac-dc supplies and its ...

Texas Instruments (TI) has unveiled what it claims is the industry’s first stand-alone active electromagnetic interference (EMI) filter integrated circuits (ICs). Intended to help engineers implement ...
