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 ...

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 ...

The continuous evolution of microelectronics tends to underestimate the importance of passive components. Actually, capacitors, resistors, and inductors play a fundamental role in all electronic ...

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 ...
