Nanocrystalline common-mode cores for power transformers

电力变压器（尤其是高频电力电子变压器）中的纳米晶共模磁芯主要用于抑制共模噪声，提高系统EMC性能，适用于新能源发电、智能电网、轨道交通等高压大功率场景。相比传统硅钢或铁氧体，纳米晶磁芯在高频、高饱和、低损耗方面表现突出。

The nanocrystalline common-mode cores in power transformers (especially high-frequency power electronic transformers) are mainly used to suppress common-mode noise and improve system EMC performance, and are suitable for high-voltage and high-power scenarios such as new energy power generation, smart grid, and rail transit. Compared with traditional silicon steel or ferrite, nanocrystalline cores have outstanding performance in terms of high frequency, high saturation and low loss.

电力变压器纳米晶共模磁芯的核心优势

The core advantages of nanocrystalline common mode cores for power transformers

•  高频低损耗：适用于高频电力电子变压器（如10kHz~100kHz LLC谐振变换器）；

High frequency and low loss: suitable for high-frequency power electronic transformers (such as 10kHz~100kHz LLC resonant converters); 

•  抗饱和能力强：适合大电流瞬态工况（如短路电流冲击）；

• Strong anti-saturation ability: suitable for high-current transient conditions (such as short-circuit current impulse);

•  温度稳定性高：可在-55℃~+150℃长期工作，适用于户外电力设备。

High temperature stability: It can work at -55°C~ 150°C for a long time, and is suitable for outdoor power equipment.
