家电共模滤波磁芯
Common mode filter cores for household appliances
家电中的共模滤波磁芯是一种用于抑制共模噪声的关键元件，主要应用于电源线、信号线等场景，以提高电磁兼容性（EMC）。
The common mode filter core in household appliances is a key component for suppressing common mode noise, mainly applied in scenarios such as power lines and signal lines to enhance electromagnetic compatibility (EMC).
共模滤波磁芯的作用
The function of common mode filtering magnetic core
• 抑制共模噪声：共模噪声是同时出现在两条信号线（或电源线）上、相位相同的干扰信号（如来自开关电源、 电机的高频噪声）。磁芯通过感抗阻碍高频噪声的传输。
• Common-mode noise suppression:Common-mode noise is an interfering signal (e.g., high-frequency noise from a switching power supply or motor) that occurs on two signal lines (or power lines) at the same time and is of the same phase. The magnetic core hinders the transmission of high-frequency noise through inductive reactance.
• 提高EMC性能：帮助家电满足电磁兼容标准（如CISPR、FCC等），避免干扰其他设备或被干扰。
• Improved EMC performance:Help home appliances meet electromagnetic compatibility standards (such as CISPR, FCC, etc.) and avoid interference with other equipment or interference.
典型应用场景
Typical application scenarios
• 电源输入端：如家电的AC电源线（如冰箱、空调、洗衣机）上套装的磁环。
• Power input: such as the magnetic ring on the AC power cord of a home appliance (such as refrigerator, air conditioner, washing machine).
• 信号线滤波：如HDMI、USB线缆上的磁芯，防止高频干扰。
• Signal line filtering: such as the magnetic core on HDMI and USB cables to prevent high-frequency interference.
• 电机驱动电路：抑制电机（如风扇、压缩机）产生的噪声。
• Motor drive circuit: suppresses noise generated by motors (e.g., fans, compressors).
