What is EMI Filters Electromagnetic interference filters (EMI Filters), also known as RFI Filters or radio-frequency interference filters, are an electrical device or circuit that reduces high-frequency electromagnetic noise on power and signal lines. There are various electrical and electronic devices, which produce high frequency noises such as motors, electronic controls, power supplies, inverters, clock circuits, microprocessors, appliances, and electronic devices.
EMI Filters Divided Into Two Parts • Radiated EMI • Conducted EMI Conducted EMI is transmitted via conductors such as wires or power lines. Radiated EMI travels through the air without the use of a conductor.
Where Can EMI/RFI Come From It can be both Natural and Man-Made. • Natural Causes: • Man-Made Causes: • Lightning • Solar flares and radiation • Dust and snow storms • Electrical storms in the atmosphere • Electric motors and generators • Power supplies • Cellular networks • Transmitters • Transformers
Types of EMI Filters Offered by Premier Filters EMI FILTERS THREE PHASE EMI FILTERS SINGLE PHASE EMI FILTERS DC EMI FILTERS TEMPEST FILTERS SCIF FILTERS MILITARY/COTS EMI FILTERS
Why Do We Need a Power Line Filter • It is required due to the use of high frequency • Because of harmonic noise created from fast changes in voltage • And unwanted current from Switch Mode Power Supplies
Process for Selecting an EMI Filter • Review Electrical and Operational Requirements • Analyze Application and System Requirements • Review Actual EMI Filtering Characteristics • Preliminary EMC Testing
What is EMI Shielding and Why is it Important for Your Design? EMI shield is a metal housing that blocks electromagnetic fields from radiating & coupling into other circuits or systems EMI shields protect electrical devices from external radiation. Gaskets, Plates, Conduits, Honeycomb vents Braids Shielding forms
EMI Filter Installation Best Practices • EMI filters are to be properly grounded/bonded to the host equipment to achieve optimum performance. • In EMI Filters Installation make a proper filter wiring and cable layout • Do a Proper EMI Filter Mounting
