EMC-Filter CNW 174
DC filter for photovoltaik (2 lines)
Description
By using efficient energy conversion in modern high-frequency inverters, more high-frequency energies are in the DC circuits. Caused by the fast switching processes of modern power semiconducators, these energies can damage the solar modules. On the AC and DC side a very high interference level will be created in the frequency range of 150kHz – 30MHz.
This fact for the DC side is not recorded in the current standards. The long DC cables and the large PV modules on the filter are special features which distinguishes the inverter to all other electronic devices.
The PV generator and the often very long DC cables function as antennae and can radiate originally conducted interference.
The electromagnetic compatibility of the inverters to other devices is guaranteed.
Advantages
- protection of solar cells from high frequency
- noise generated by the inverter
- designed to conform to existing and planned
- optional with current transformer
- compact construction
- low temperature rise
- universal protection for all inverters
- optional anti-surge protection
Typical applications
Applications: The DC-filter surpresses grid-bound troubles of inverters for renewable energies like solar and wind power.
