据2014年8月14日消息,TDK株式会社最新推出了适用于再生式变频器系统的爱普科斯(EPCOS)高性能LCL滤波器(B84143*405)系列产品。该系列滤波器由一个电源扼流圈、带阻尼电阻器的电容器组以及一个牢固的扼流圈组成,其滤波器电路能够大幅减弱时钟频率,完全符合IEC/TS 62578标准有关EMI发射范围为9~150 kHz的设备规定。此外,在再生式变频器系统中,爱普科斯LCL滤波器还可以显著降低线侧电流谐波(低于5%)。最后,在高直流链路(DC link)电压应用下,
According to a press release on August 14, 2014, TDK Corporation recently introduced the EPCOS high-performance LCL filter (B84143 * 405) series for use in regenerative drive systems. The series of filters consists of a power choke, a capacitor bank with damping resistors and a robust choke, whose filter circuitry drastically reduces the clock frequency in full compliance with IEC / TS 62578 for an EMI emission range of 9 ~ 150 kHz device regulations. In addition, EPCOS LCL filters can significantly reduce line current harmonics (less than 5%) in regenerative drive systems. Finally, under high DC link voltage applications,
