The IEEE's Applied Power Electronics Conference (APEC) is a must-go event for designers who need to keep up with the latest power-related technologies, products, and design practices. So, it's no ...
Filters are circuits comprising resistors, inductors and capacitors that pass certain frequency bands and attenuate others. Active filters use operational amplifiers (op amps) with resistors and ...
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 ...
