摘要
阐述了应用于直流电动机的电容滤波的三相不可控整流电路的工作原理,并给出了带滤波电感和不带滤波电感情况下的工作原理的区别,最后借助仿真软件对其理论进行了比较分析。通过仿真结果分析得到:不带电感的电容滤波的三相不控整流电路在wRC≥(3)^(1/2)时,输出电路出现断续。另外带滤波电感的直流侧输出电压脉动明显小于不带滤波电感的电路。
The working principle of three-phase uncontrollable rectifier circuit applied to the capacitance filtering of DC motor is described, and the difference between the working principle with filter inductance and without filter inductance is given. Finally, the simulation software is used to compare the theory analysis Through the simulation results obtained that the output circuit is intermittent for the capacitor filter three-phase unregulated rectifier circuit without inductance when ωRC≥√3. In addition with the filter inductor DC side of the output voltage ripple is significantly less than without filter inductor circuit.
