六、應用原理及實例介紹( Principle and practical application):


1.變頻傳動變頻器(Variable-frequency Drive Device )


變頻器是應用變頻技術與微電子技術,通過改變電機工作電源頻率方式來控制交流電動機的電力控制設備。變頻器主要由整流(交流變直流)、濾波、逆變(直流變交流)、制動單元、驅動單元、檢測單元、微處理單元等組成。變頻器靠內部IGBT的開斷來調整輸出電源的電壓和頻率,根據電機的實際需要來提供其所需要的電源電壓,進而達到節能、調速的目的,隨著工業自動化程度的不斷提高,變頻器也得到了非常廣泛的應用。低磁導率納米晶大共模電感鐵芯適用于≤1000V的低壓變頻器,能有效抑制變頻器產生的共模干擾。

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.光伏發電逆變器( PV Inverter)


       適用于500kW、1MW大功率集中式光伏逆變器。高磁導率大共模電感鐵芯適用于大功率光伏逆變器交流側EMC濾波,利用鐵芯的高電感能有效減少鐵芯數量達到很好的濾波效果;低磁導率大共模電感鐵芯適用于大功率光伏逆變器直流側EMC濾波,該類鐵芯電感頻率特性好,能有效抵抗不平衡直流分量,避免鐵芯飽和造成的燒毀。

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.風力發電變流器(Wind Power Converter )


適用于1MW、1.5MW、2MW、3MW等直驅和雙饋變流器。采用數只納米晶鐵芯堆垛組裝的單匝扼流圈是軸承電流問題的有效解決方案,也是風力發電、大范圍變速驅動及其他應用產生的大電流干擾(峰值從幾十到100多安培)導致的超高共模噪音問題的有效解決方案。這些問題通常表現為高頻尖峰電流的形式。安泰科技股份有限公司生產的共模組件能輕松安全的集成到這些現有領域解決出現的問題。共模組件可由兩種不同內徑的磁環裝配而成。組件按所需的飽和電流和電感定制設計,允許單選磁環,也可數只組裝(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).

4.電動汽車/混合動力汽車(EV/PHEV)


納米晶共模電感越來越多地應用在純電動汽車和混合動力汽車的車載充電機中。在溫度高達180℃時,納米晶鐵芯可安全和長期運行;受其應用溫度范圍~100℃限制,鐵氧體鐵芯不能滿足使用要求。

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.氣體絕緣開關設備(Gas insulated switchgears)


氣體絕緣開關設備(GIS)是非??煽康碾娏鬏斁W絡的組件。在過去的幾年,系統電壓達到1.2千伏。GIS的切換操作可能導致危險的瞬態電壓(VFTO)。在內部導體上同心的安裝納米晶鐵芯作為單匝的電抗器,可以有效地抑制這些破壞性的高頻(~15 MHz)電壓。其他的鐵芯材料如鐵氧體不能解決這個問題。

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)


由于納米晶具有至少1.2特斯拉的高飽和磁通密度,適當的納米晶鐵芯是同步回旋加速器空腔調諧組件的首選解決方案。在非常有限的空間進行的粒子束偏轉集束器或壓縮集束器,通過使用納米晶鐵芯,所需的長度比鐵氧體鐵芯通??梢詼p少50%,但缺點是工作期間功耗顯著增加。不過,由于他們的低阻抗,納米晶鐵芯也避免了與離子束不利的交互作用,因此,納米晶鐵芯在全世界的幾個粒子束加速器設施中得以使用。

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.
