| 摘 要： | 分析了一种利用LC谐振来实现低输入电流谐波的三相不控整流器,它利用交流侧串联电感与整流桥上桥臂二极管的并联电容谐振来改善输入侧电流,电路结构较为简单.与传统的三相整流器相比,该整流器可显著降低输入电流的谐波含量,得到近似为1的高功率因数.详细分析了该整流器的工作原理和特性,并给出了参数设计方法及电路的优缺点.仿真和实验证明了结论的正确性.

| Abstract: | An analysis of a three-phase low-harmonic diode rectifier based on LC resonant circuit with inductors,capaci-tors,and diodes is presented.The waveform of the input current has been improved greatly compared with the classical rec-tifier.The converter's operational principle,characteristics,design method and characteristics are illustrated.The simulative and the experimental results show good agreement with the conclusion. |
