Sinusoidal filter – TRAMAG products explained

Just like dU/dt filters, Sinusoidal filters belong to the output filters, as they are also operated directly at the inverter output and before the connected drive units (motors).

24. May 2022

dU/dt filters – TRAMAG products explained

dU/dt filters belong to the group of output filters, as they are used directly at the inverter output, upstream of the connected drive units – developed precisely to fit the individual drives system.

LCL filters – TRAMAG products explained

LCL filters are operated directly upstream of the converter to the grid feed-in side. They are used specifically for regenerative converter solutions, which is why they are also used primarily in the field of renewable energies in photovoltaics.

Connection technology – made by TRAMAG

The quality of transformers, chokes and filters depends to a large extent both on their materials and on how these materials are combined and connected.

Magnetic core technology – made by TRAMAG

Due to our own production of magnetic cores from electrical sheets, we can flexibly respond to customer requests in the given installation space and thus make transformers and chokes deeper, higher or wider, for example.
