Advantages through the use of filters:
ƒ
Compliance with EMC requirements
ƒ
Reduced current load
ƒ
Positive effects on the service life of the controller possible
– Stable reliability
– Reduced failure rate
Mains chokes:
Inductances for damping conducted harmonic interferences which may arise from
reloading the DC bus and the switching frequency of the inverter.
RFI filters:
RFI filters are capacitive accessories for compliance with the requirements acc. to
EN 61800-3 for conducted interference emission. RFI filters can be directly connected
upstream of the power supply modules. RFI filters are also called EMC filters.
Mains filters:
Mains filters reduce the conducted interference emission into the mains for compliance
with the requirements acc. to EN 61800-3. Mains filters are a combination of mains choke
and RFI filter in one housing.
A sinusoidal filter (LC filter) in the motor cable limits the rate of rise of voltage and the capacitive
charge/discharge currents which occur during inverter operation. This enables considerably longer shielded
motor cables and the service life of the motor is increased.
