8.1 Definition
Electromagnetic compatibility refers to the ability of electrical equipment to opera-
te in an electromagnetic interference environment without interfering with the ele-
ctromagnetic environment and to stably achieve its functions.
8.2 Introduction to EMC Standards
According to the requirements of the national standard GB/T12668.3, the inverter
needs to meet the requirements of electromagnetic interference and anti-electro
-
magnetic interference.
Our existing products implement the latest international standard: IEC/EN61800-
3: 2004 (Adjustable speed electrical power drive systems part 3: EMC requirem
-
ents and specific test methods), which is equivalent to the national standard GB/
T12668.3.
IEC/EN61800-3 mainly inspects the inverter from two aspects: electromagnetic
interference and anti-electromagnetic interference. Electromagnetic interference
mainly tests the radiated interference, conducted interference and harmonic inte
-
rference of the inverter (for domestic inverters, there are requirements). The anti-
electromagnetic interference mainly affects the conducted immunity, radiation
immunity, surge immunity, rapid mutation pulse group immunity, ESD immunity
and low frequency end immunity of the power supply of the inverter (specific test
items are: 1 , Input voltage sag, interruption and change immunity test; 2. Com
-
mutation notch immunity test; 3. Harmonic input immunity test; 4. Input frequency
change test; 5. Input voltage unbalance test; 6. Input voltage fluctuation test) to
test. Tested in accordance with the strict requirements of IEC/EN61800-3 above,
our products are installed and used in accordance with the instructions shown in
8.3, and will have good electromagnetic compatibility in general industrial envir
-
onments.
8.3 EMC Guidance
High-order harmonics of the power supply will damage the inverter. Therefore, in
some places where the quality of the power grid is relatively poor, it is recomm-
ended to install an AC input reactor.
