FREQCON NGC
Next Generation Converter

Leading Edge Converter Technology for Wind, Solar and Grid Support Applications

FREQCON NGC Applications

FREQCON Next Generation Converters offer high efficiency and a cost effective solution, and come as full size 2-Q or 4-Q converters for all generator designs (synchronous generator, induction generator) for wind, hydro, cogeneration units and diesel gene-rators.

The system is used as solar converter, providing a centralized design with high voltage DC-bus for saving cable costs.

FREQCON NGC as battery to grid converter for smart charging and discharging provides a wide range of battery types, such as Li, LiFePO4, lead-acid, sodium-sulfur and zinc-oxygen and double layer capacitors.

Redundant multi-converter system

Multi-level, high voltage converter up to 2400VDC

Reactive power compensation for high dynamic grid voltage control

Harmonic filtering

Grid support applications according to BDEW2008, TC2007, TR8 FGW, DS3
