RE: on line filter
1. To improve quality of power supply, e.g. mitigate voltage or current or both power supply side harmonics; and
2. To mitigate voltage or current or both distortions caused by nonlinear loads.
3. If the filter is small, it could suppress electromagnetic interference, i.e. it could be an EMI filter.
