Emi Filter, or electromagnetic interference filters, also called RFI Filters or radio-frequency interference filters, are an electrical device / circuit that mitigate the high frequency Electromagnetic noise present on the power and signal lines. The high frequency noise is generated by a variety of electrical and electronic devices such as motors, electronic controls, power supplies, inverters, clock circuits, microprocessors, appliances, electronic devices etc. This noise is typically in the 9KHz to 10GHz frequency range and it can degrade or prevent the signal transmissions and/or the intended performance of an electrical/electronic equipment. The lower frequency components of the EM noise can impact the power quality as well.
With this characteristic of the EMI filter, a square wave group or composite noise passing through the power supply filter can be converted into a sine wave of a specific frequency.
The noise to be suppressed by the line filter can be divided into the following two types:
1) common mode: The same noise on two (or more) power lines can be seen as the noise of power lines to the ground.
2) differential mode: Noise between power lines
An EMI filter will have different suppressing capabilities for common mode noise and differential mode noise, and will generally be described by the spectrum of the frequency corresponding to the suppression (in decibels).
