LCL filter must be connected between AFE and the AC line supply.
It reduces the harmonics related to the switching frequency of the IGBT power
bridge (high order harmonics).
Decreasing the harmonic current distortion, It improves the line power quality and
its voltage distortion.
The specified LCL filters refer to the default value of the AFE200 switching fre -
quency. This frequency must not be changed .
(1) LCL filter for sizes (AC input 400…480Vac and 690Vac):
• From size AFE200-3220 to 71600 configuration HD (160kW ovld 150%)
• From size AFE200-3220 to 61320 configuration LD (160kW ovld 110%)
is composed by one choke connected on the AFE line input ( LR3-AFE) and one
LC device ( LC-AFE ) composed by a capacitors bank and a line choke in a single
package
(2) LCL filter for sizes (AC input 400…480Vac and 690Vac):
• From size AFE200-72000 to 73550 configuration HD (355kW ovld 150%)
• From size AFE200-71600 to 73550 configuration LD (400kW ovld 110%)
• All Parallel configuration
is composed by one choke connected on the AFE line input ( LR3-AFE ), and
one LC device ( LC-AFE ) composed by a capacitors package ( C-AFE ) and a line
choke ( L-AFE )
Note !
