Aurora grid-tie transformerless wind inverters offer a unique combination of ultra-high efficiencies, installer-friendly designs and long service life.
A major selling point of the Aurora Wind inverter is its very wide input voltage range ensuring power is continuously harvested from the lightest breeze to the strongest wind. This high-frequency isolated three-phase unit allows for a direct parallel connection of multiple units, allowing for small wind applications for up to 50kw. The competitive initial acquisition costs matched with the high efficiencies of up to 96.4% wide input range significantly increase return on investment on wind-power installations. This compact, weather-sealed inverter has a 16-point profile to best match the power curve of each wind turbine. Wind Interface box is an optional accessory.
This new product to Power-One’s Aurora wind accessories offers more flexibility for small wind applications.The 25kW wind interface is designed to be a ‘smart’ rectifier which once programmed with the turbine’s power curve it can control the output of single or multiple inverters allowing scalability for installation. Additionally it provides over-voltage protection and drives a dumpload braking system.
Aurora grid-tie inverters offer a unique combination of ultra-high efficiencies, installer-friendly designs, long service life, and competitive initial acquisition costs; significantly increasing -return on investment in wind-power RE installations.
Following the growing demand for wind power and the market trend to introduce higher power turbines using “In-Line Technology”, the Power Converter Unit will be a real “core” component of the turbine permanent magnet generator system in the upcoming years.
The OEM’s need of reducing installation cost per kWh and the trend of developing highly-specialized components manufactured to specification have brought Power-One to introduce its new medium voltage 2.5 MW inverter module, the LSWI-2.5MW. This inverter module has been developed to meet the highest technology needs for turbine-to-grid interface which include using an innovative IGBT-based design that incorporates Power-One’s industry-leading technology for renewable energy inverters.
