Instead, designers should perform tests and take measurements to determine their actual filter needs for their application. Power supply manufacturers such as XP Power can help, offering a range of AC ...

The Corcom brand single- and three-phase filters are designed for high current applications ranging from 30-400 A. The new BCF Series includes seven three-phase filters with current ratings of 30-180 ...

A new IC-based approach to EMI filtering in ac-dc power subsystems dramatically cuts inductor size and offers other benefits as well.

X- and Y-capacitors are commonly used to filter AC power-source electromagnetic interference (EMI) noise and are often referred to as safety capacitors. Here is a detailed view of these capacitors, ...

Using both active and passive filters, the signal can be separated from the AC power and decoded. This system uses frequency-shift keying to encode data.
