6.4.3 Using several single-phase converters in machines and plants
Overview
Evaluate the input currents of single-phase converters in your machine or plant in terms of
harmonics and unbalance.
Description
In unfavorable cases, the harmonic currents of several converters in the neutral conductor (N)
add up to a value greater than the currents of the line conductors (L1, L2, L3). The current-
carrying capacity of the neutral conductor must be su󹪟cient for this.
