The aim of the project is the development and manufacturing of a multi megawatt converter system that not only complies with state-of-the-art requirements and features within the wind turbine industry, but also significantly lowers the cost compared with the prices known from the industry today.
The project succeeded by developing a new Converter system that reaches the targets in terms of efficiency and cost, by achieving a medium voltage system with the same cost as a low voltage design. The project demonstrated scalability with a kW demonstrator and efficiency and cost with a full scale 6MW version.
The main challenge for the project is to combine the technical benefits from various known systems and expand these to the future turbine needs
Looking at the market today the common systems available are divided into cost competitive, low-voltage, two-level converter systems, and various medium-voltage systems that in some applications can offer increased system efficiency but normally also at a higher cost.

The main challenge for the project is to combine the technical benefits from various known systems and expand these to the future turbine needs without compromising with the overall driver of keeping the cost of the system at a minimum.
The Modular Multi-level Converter shows several advantages, such as scalability, high modularity, low switching losses, low Total Harmonic Distortion and high reliability. Thanks to these benefits, this topology has become a promising solution in several applications, like in High Voltage Direct Current, static compensators and in high-power motor drivers.
This project is contributing to the long-term objective to convert the Danish energy system to be 100 % based on renewable energy, of which the exploitation of wind energy has been a key driver
Also new market possibilities such as Onshore Power Systems for the maritime market are in progress since the multi-level design also provides some interesting features towards supply and charging of electrical and hybrid ships.
For system verification and future cooperation, we are looking for a suitable test partner.
