6-2.EMC (Electromagnetic compatibility)
6-2-1.Definition
Electromagnetic compatibility refers to the ability that the electric equipment runs in an
electromagnetic interference environment and implements its function stably without interferences
on the electromagnetic environment.
6-2-2.EMC standard
In accordance with the requirements of the Chinese national standard GB 12668.3-2012/IEC
61800-3:2004, the inverter must comply with the requirements of electromagnetic interference and
anti- electromagnetic interference.
Our existing products adopt the latest international standards: IEC/EN61800-3: 2004
(Adjustable speed electrical Power drive systems Part 3: EMC requirements and specific test
methods), which is equivalent to the Chinese national standards GB 12668.3-2012/IEC 61800-
3:2004. EC/EN61800-3 assesses the inverter in terms of electromagnetic interference and anti-
electronic interference. Electromagnetic interference mainly tests the radiation interference,
conduction interference and harmonics interference on the inverter (necessary for civil inverter).
Anti-electromagnetic interference mainly tests the conduction immunity, radiation immunity,
surge immunity, EFTB(Electrical Fast Transient Burs) immunity, ESD immunity and power low
frequency end immunity (the specific test items includes: 1. Immunity tests of input voltage sag,
interrupt and change; 2.Commutation notch immunity; 3. harmonic input immunity ; 4. input
frequency change; 5. input voltage unbalance; 6. input voltage fluctuation). The tests shall be
conducted strictly in accordance with the above requirements of IEC/EN61800-3, and our products
are installed and used according to the guideline of the Section 6-3 and can provide good
electromagnetic compatibility in general industry environment.
