HF Sine Filter Module

5.4.1

Description

The HF Sine Filter Module is the output filter (sine-wave filter) in the High Frequency Drive. It
limits the harmonics and switching edges generated by the switching operations of the inverter
to values that are permissible for the motor and can be tolerated. It opposes an excessively high
dV/dt rise.
The HF Sine Filter Module comprises a HF Choke Module and a HF Damping Module. This filter
means that the voltage between the motor terminals is almost sinusoidal. This reduces the
voltage stress on the motor windings, which is excited by the pulse frequency of the HF Motor
Module.
The HF Sine Filter Module must be mounted directly to the right of the HF Motor Module.
