| 摘 要： | 电容滤波直流电源电路在工作过程中会产生比较严重的谐波电流,这些谐波电流的存在会给后端电路和供电系统带来危害。对此,首先对电容滤波直流电源电路中谐波电流的产生机理进行了分析,然后针对这些谐波电流给出了两种基于LC谐振滤波的谐波抑制方法,并对其抑制性能进行了仿真和实验验证。结果表明,两种LC谐振滤波的谐波抑制方法均可有效降低直流电源电路中谐波电流的占比,并显著提高电源有用输出功率。

| Abstract: | The capacitor filter DC power circuit will produce serious harmonic current in the working process, which will bring harm to the back-end circuit and power supply system. In this paper, the generation mechanism of harmonic current in capacitor filter DC power supply is analyzed firstly, and then two harmonic suppression methods based on LC resonance filter are proposed for these harmonic currents, and their suppression performance is verified by simulation and experiment. The results show that the two harmonic suppression methods of LC resonance filter can effectively reduce the proportion of harmonic current in the DC power supply circuit, and significantly improve the useful output power of the power supply. |
