Minimum Line Impedance
Always add a line reactor when capacitors for power factor
correction are installed in the same line and near to the
inverter.
Figure 8.29 shows the line reactorconnection to the input.
Use the following equation to calculate the value of the line
reactor necessary to obtain the desired percentage of the
voltage drop:

- Minimum network impedance for several load conditions
Note:
These values ensure a life of 20,000 hour for the DC link capacitors, i.e., they
can be operated during 5 years with operation of 12 hours per day.
