Worldwide Business Survey: Global Industry Power Electronics for Wind Turbines Market Forecast, 2013 - 2019

The increase in consumption of the electrical energy by two percent per year has boosted the growth of the renewable sources. By 2060, around half of the world’s electrical energy is expected to come from wind turbines stations. Wind energy is now the world's leading growing energy source. The continuous growth in the wind energy industry can be attributed to the research and development of innovative cost-reducing technologies and concerns to the environmental issues. Power electronics in the wind turbines contributes to the largest share of power electronics market. The change in the turbine architecture and convertors with an aim at greater efficiency and reducing operations and maintenance cost is contributing to the growth of this market.




With the need of lighter, cheaper and more efficient system, there are four technologies which are best suited for handling new system requirement such as silicon IGBT, Silicon Carbide (SiC)-based devices, Super Junction (SJ) MOSFETs, and Gallium Nitride (GaN). The major applications of power electronics in wind turbine are for adjustable (variable) speed motor drives, power generation plants, and power transmission & distribution systems. They are used in making power modules, stack assembly, power converter. Power electronics used in wind turbine include passive components such as laminated busbars, connectors, power capacitors, power resistors and wind convertor components such as stack, power module, IGBT stacks, IGBT, IGCT, and SiC.

The rising demand of the full convertor is driving the market forward. Innovations and technological up-gradation is one of the factors contributing to the growth of the market. Companies such as Infineon has introduced copper into the module, for die attach and connections and also introduction of the silver into power modules by Semikron is driving the market forward. Competitive environment and need of cost grades are some of the challenges faced by the new players who are trying to enter into the market. China is the largest market for this industry. The change in industry over the period of past five years has made China the leading contributor. Asia Pacific including China is having quicker growth and is expected to be the key market in the near future. European nations hold the second largest share in driving the market forward followed by EMEA and South America.
