摘要
介绍了阻波高通滤波器的结构和工作原理,研究了其阻波性、高通性以及谐振抑制特性,并在功率特性、滤波特性等方面与既有的3种高通滤波器进行分析比较,验证既有3种高通滤波器存在工频损耗大、对外交流无功功率等缺点,而阻波高通滤波器具有工频高阻、高频低通、不与系统交流无功功率和低损耗等优点,适用于功率因数接近于1的系统。
In this paper the structure and working principle of its new filter is introduced, and compared with three high-pas filters the characteristics of wave trapped, high-pass and resonance suppression are researched. By means of comparative analysis, the advantages of high impedance in work frequency, low impedance in high-order harmonics, no exchanging reactive power with the system and low loss are verified, and the new filter applies the high-speed electrified railway.
