DRIVES AND FREQUENCY CONVERTERS
Low-voltage frequency converters 1–3 MW (including for direct-drive wind turbines)
Country: France · Model: LV frequency converters 1-3 MW
Low-voltage frequency converters rated 1–3 MW for synchronous and induction machines, voltage up to 1000 V. The main niche is direct-drive wind turbines, where the whole generator power passes through a full-scale converter. They are also suitable for industrial drives up to several megawatts.

Description
In the direct drive scheme a low-speed multi-pole generator is coupled to the wind rotor without a gearbox, so the converter takes the entire load. The manufacturer has its own experience in this field. As early as 1999 it installed the first French direct-drive wind turbine J48 of 750 kW in Widehem, and in 2015 it joined the Ecoswing consortium, which built the first superconducting generator machine of 3.6 MW. Control systems are built, as far as possible, on standard and open solutions, which simplifies long-term maintenance. Specific voltages and topology of the low-voltage converters are not given and are agreed for the project.
How to choose
First compare the generator or motor power with the range of 1–3 MW. Then check the voltage, since the series is low-voltage, up to 1000 V, and higher voltages need another design. The machine type, synchronous or induction, and the scheme with or without a gearbox affect the topology, so it is fixed in the project. For direct-drive wind turbines the converter must be full-scale, and for industrial drives a typical variant is enough.

FAQ
What power are these frequency converters made for?
From 1 to 3 MW. For industrial drives they are used up to several megawatts.
Which machines can be connected to these converters?
Synchronous and induction motors and generators.
Why does a direct-drive wind turbine need a full-scale converter?
The generator is coupled to the rotor without a gearbox, and all the power produced passes through the converter.
What voltage do low-voltage converters of this series have?
Low, up to 1000 V. Specific voltages and topology are agreed for the project.
