3.28 SWITCHING THREE-PHASE INDUCTANCE

A three-phase inductance is to be inserted into the power supply line. The inductance is aimed at:
- Reducing the mains voltage distortions from the sinusoidal form in the drive connecting point.
- Reducing the line current gradients which may cause both radio interferences and induced interferences
in the close lines.
Two series of three-phase inductances are available, named L2 and L4.
They have a different inductance value, i.e. a different phase drop (approx. 6V for the L2-type and 1V for
the L4-type): L2-type shows a better performance than L4-type.
The table below shows the inductance specifications depending on the converter size and by referring to
the power supply voltage values to be applied.
