AT&M will select ribbon with suitable composition and level to wind cores based the performance requirements from customers. Then cores will be annealed in magnetic field to meet customers’ requirements. Finally cores will be packaged according to customer’s requirements.



大富豪棋牌下载安装High saturate induction—reduce volume of CMC


大富豪棋牌下载安装Excellent impedance frequency characteristic  


Outstanding ability to resist unbalanced current  


Excellent thermal stability 



大富豪棋牌下载安装Nanocrystalline alloy has higher Curie temperature compared with ferrite and can stably work even at 180℃; It has higher permeability and saturated inductance. The weight and volume of the nanocrystalline cores are reduced. Usually, the power loss of copper windings is only 50 - 70% of ferrite. Nanocrystalline cores are widely applied to variable frequency drive, EV controller , air-conditioner, LCD TV, induction cooker and other consumer electronics as well as EMC solution of industrial power supply such as welding machines.

六、应用原理及实例介绍( Principle and practical application):

1.变频传动变频器(Variable-frequency Drive Device )


大富豪棋牌下载安装Frequency converter is electricity control equipment which uses variable and micro electronics technologies to control an AC motor through changing frequency of power supply for the motor. It is composed of rectifier (AC-DC), filters, inverters (DC-AC), brake unit, drive unit, test unit, micro-processing unit, etc. It adjusts the output voltage and frequency by switching internal IGBT and provides required power supply voltage for energy conservation and speed control. It is widely applied as the industrial automation improves continuously. Low-frequency common mode choke cores are used for low voltage inverter(≤1000V) and effectively suppress the interferences. 


2.光伏发电逆变器( PV Inverter)

大富豪棋牌下载安装       适用于500kW、1MW大功率集中式光伏逆变器。高磁导率大共模电感铁芯适用于大功率光伏逆变器交流侧EMC滤波,利用铁芯的高电感能有效减少铁芯数量达到很好的滤波效果;低磁导率大共模电感铁芯适用于大功率光伏逆变器直流侧EMC滤波,该类铁芯电感频率特性好,能有效抵抗不平衡直流分量,避免铁芯饱和造成的烧毁。

AT&M CMC Cores are applied to 500KW & 1MW centralized PV inverters. High-permeability CMC Cores are applied to EMC filters near to AC output of high-power PV inverters. The better EMI suppression effect can be reached by less quantity of CMC cores due to high induction performance. Low- permeability CMC cores are applied to EMC filters near to DC output of high-power PV inverters. Low-permeability CMC cores have excellent inductance performance depend on frequency and effective anti-DC bias performance to avoid the damage from saturated inductance.


3.风力发电变流器(Wind Power Converter )

大富豪棋牌下载安装适用于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。安泰科技股份大富豪棋牌下载安装 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.


5.气体绝缘开关设备(Gas insulated switchgears)

大富豪棋牌下载安装气体绝缘开关设备(GIS)是非常可靠的电力传输网络的组件。在过去的几年,系统电压达到1.2千伏。GIS的切换操作可能导致危险的瞬态电压(VFTO)。在内部导体上同心的安装纳米晶铁芯作为单匝的电抗器,可以有效地抑制这些破坏性的高频(~15 MHz)电压。其他的铁芯材料如铁氧体不能解决这个问题。

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). Other materials cannot solve this problem such as ferrite.


6.高能粒子加速器(High energy particle accelerator)


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.
