Description

LCL filters are used to connect AIC (active infeed converter) and AFE (active front end) drives to the mains.

Due to the increasing use of AFE / AIC, more LCL filters are needed.

It can also be run as an LC filterThe LCL filters are also of interest for projects in the DC-AC product range, which feed electric energy from wind generators or PV inverters into the grid. Applications of regenerative AFE drives are lifts, cranes or similar transport systems, tools or other machines with many brake switching cycles and presses.

We develop, design, calculate and build filters according to your specifications, depending on the location.
