EMC Filter Function

The EMC filter (Pi Filter board) is designed to make the generator compliant with the EMC conducted noise and immunity regulatory by filtering the HV power inverter noise (rotation noise is mainly filtered on the rotation board).

It is placed at the power input of the generator and mainly composed of one to several (L,C) filters and common mode inductor.

Refer to the block diagrams in kV Function, Rotation Function, or Power Supplies Distribution. These show where the Pi Filter board is used.
