摘　　要：文章分析了单相整流滤波电路对交流侧产生谐波的情况,发现以增加滤波电容来改变滤波效果时,却对交流侧产生更明显的谐波,其THD值也越大,所以在设计整流滤波电路时应权衡考虑,并且可以通过在直流侧串入电感减小电流的冲击。This article analyzes the situation that the single-phase rectification filter circuit has the harmonic on exchange side,discovers that when changed the filter effect during the increase filter electric capacity,actually the harmonic on exchanged side is more obvious,its THD value is also bigger,therefore it should measure the consideration in design rectification filter circuit,simultaneously it points out entering the inductance in the direct-current side can reduce the electric current impact.

关 键 词：整流滤波 交流侧 谐波 改进
