Depending on the field of application, DC drives can be a cost-effective alternative to AC drive technology with frequency converters. In these cases too, SIDAC reactors and filters make a significant contribution – the operational reliability and availability of converter systems is significantly enhanced.

You can see where and when to use each device from the following overview.

Line harmonics under control:
SIDAC network/commutating reactors and SIDAC RFI suppression filters

For frequency converters or DC converter drives: the phase effects on the system are similar. The same components are therefore used on the line side as for AC drives: Network and commutating reactors as well as RFI suppression filters. With large DC drives, in particular, a sufficiently large inductance is essential – a requirement that SIDAC reactors and filters optimally satisfy with their rugged construction and high availability.

Reliable reduction of current ripple: SIDAC smoothing reactors

Typical applications for DC drives are the main drives of printing machines, rolling mills or winding drives as well as traversing and lifting drives in the lifting gear industry. SIDAC smoothing reactors reduce the current ripple in the motor circuit extremely reliably. The reactors are available from the kW to MW range.
