Full-power converters

FPC5000 and FPC6000

The Switch full-power converters (FPC) are optimized to work with our permanent magnet generators. Designed for the highest-level performance in wind power generation, the robust line inverters ensure future-proof electricity quality to meet the ever-stricter network requirements for harmonics, flicker and fault ride-through (FRT).

The Switch FPCs enable easy power factor control. This means that all the current can be used for active or reactive power generation, allowing a 100% reactive power feed, even in the absence of wind.

Because The Switch FPCs are not as sensitive to changes in the network as traditional converters, they offer advantageous control flexibility for adapting to ever-changing operating conditions.

Features	Advantages
Modular design	Matches all wind conditions and power requirements with quick power adaption
Generator inverter	Adjusts generator power factor using an active rectifier and maximizes generator efficiency
Line inverter	Outstanding fault tolerance and grid support through FRT functionality for stable and high-quality electricity
LC filter	Specifically designed for line inverter resulting in extremely low harmonics
Control unit	Various field bus options for easy integration with turbine controller
Rugged IP54-class cabinet	Designed for harsh conditions and easy access

Specifications

Different power levels are possible by using similar mechanical designs. The power can be increased simply by duplicating the number of cabinets. This modularity allows easy handling during setup, replacement and maintenance.

Technical drawings

The modular design allows full redundancy. Failure of one converter does not cause any turbine downtime. The turbine continues operation at a lower power production rate.
