The GRIDCON ACF Industrial version is a 3 wire Active Harmonic Filter and belongs to the new generation of Active Harmonic Filters GRIDCON ACF. The GRIDCON ACF active filters use a new 3 - level technology. The 3-level circuit of GRIDCON® ACF is based on twelve IGBTs, whereas conventional 2-level active filters only comprise of six. The special circuitry halves the voltage load of the power semiconductors. On the one hand this results in lower losses and on the other hand enables use in grids with a higher rated voltage. The DC link voltage is also higher which allows higher peak currents to be generated, which succeed Low losses and high dielectric strength. Also, it is an expendable device, which with a combination of several cabinets can reach 3 Mvar of needed power. The optimized power electronics enable use in a wide voltage range of less than 380 V to more than 690 V. Given the isolated main cooling duct and low losses, reliable operation is possible under demanding environmental conditions. The modular concept simplifies subsequent expansion or modification, allowing the filters to grow with their tasks. The operator can perform parameterization for new or changed tasks himself, ensuring long-term flexibility. GRIDCON® ACF Industrial version is already prepared for future functionality to compensate harmonics even beyond the 51st.
