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).

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.
