Compact, low loss EMC filters for photovoltaic applications

Schaffner is introducing the new FN 22xx HV and FN 33xx HV standard filters for high-current applications for 690V AC and 1500V DC PV inverters, converters and motor drives. These innovative filters are optimised for the requirements of photovoltaic, power conversion, energy storage and motor control systems and take into consideration Schaffner's extensive global application experience with AC and DC power systems.

Together with appropriately sized 690V AC EMC/EMI filters FN 331x HV on the line side, the new FN 221x HV DC filters help to meet the limits of binding EMC standards for PV installations in Europe and other regions. Further, the 1500V DC filter FN 221x HV will help to increase the service life of the solar panel, improve its reliability, and reduce potential interference radiations of the panel, by keeping away the inverter-born high-frequency and leakage currents.

FDIS recently approved the new international CISPR11, Ed.6.0 standard, which defines now the conducted emission limits at the DC power ports of "Grid Connected Power Conditioners".

The compact AC filters FN 331x help to meet the already well-known EMC standards, and are optimised to suit the most modern inverter design requirements of various power converter types.

These new filters will require much less installation space compared with traditional filters, due to the optimised attenuation performance levels. They also offer minimum power loss related to the rating of the inverter and thus help to maximise the system efficiency.

Both bus-bar filter series are available with ratings from 250A to 2300A. Versions without capacitors to ground are also available as standard product for specific AC and DC power system requirements. All models are CE, UL, CSA and ENEC (FN 331x HV) approved and RoHS compliant.

More detailed information about the FN 22xx HV and FN 33xx HV standard filters is available on www.schaffner.com and from all Schaffner partners.
