3.风力发电变流器 (Wind Power Converter)
适用于1MW、1.5MW、2MW、3MW等直驱和双馈变流器。采用数只纳米晶铁芯堆垛组装的单匝扼流圈是 轴承电流问题的有效解决方案，也是风力发电、大范围变速驱动及其他应用产生的大电流干扰(峰值从几 十到100多安培)导致的超高共模噪音问题的有效解决方案。这些问题通常表现为高频尖峰电流的形式。 安泰科技股份有限公司生产的共模组件能轻松安全的集成到这些现有领域解决出现的问题。共模组件可由 两种不同内径的磁环装配而成。组件按所需的饱和电流和电感定制设计，允许单选磁环，也可数只组装(最 多 7 只 ) 。
AT&M CMC Cores are applied to direct-drive and double-fed converters covering 1MW 、1.5MW 、2MW、 3MW,etc.The choke design of stacking several nanocrystalline cores are effective solution for big bear current problems.Meanwhile it is also effective EMI solution caused by big current interfere(dozens to more than 100 A)for wind energy,variable-speed drive and other application. All those problems usually are reflected in high-frequency peak current and easily solved by AT&M stacking CMC cores design.The stacking ways are depend on saturated current and induction.
Customer can select one core or stacked cores(up to 7 cores).
Nanocrystalline common mode is more and more applied to on-board charger of the battery electric vehicle and Hybrid Electric Vehicle.Even under temperature as high as 180℃,Nanocrystalline cores can work safely over long term;restricted by the temperature limit of around 100℃,ferrite cores can't meet the requirement.
GIS is reliable equipment for power transmission.The system voltage has been up to 1.2KV during past years.The switch operation of GIS may lead to danger VFTO.The reactors with nanocrystalline cores can prevent the damage from high frequency voltage(~15 MHz).0ther materials cannot solve this problem such as ferrite.
Due to the high saturation flux density of at least 1,2Tesla suitable nanocrystalline cores are the preferred solution for the tuning elements in synchrotron cavities.Related applications like particle beam de-bunchers or bunch compressors are often very much limited in space.By the use of nanocrystalline cores,the required length compared to Ferrite cores can be reduced by typically 50%-but with the disadvantage of significantly higher power consumption during operation.But due to their low impedance,the nanocrystalline cores also avoid unfavorable interactions with the ion beam and thus,they are used in several particle beam accelerator installations worldwide.
