摘要
设计了基于Multisim的整流滤波仿真电路,避免了实际电路更换元器件的不便及潜在危险,可以更透彻地研究整流与滤波。通过搭建仿真电路并调节相关器件参数,直观呈现了整流滤波的波形,分析了整流后电压与理论值有差异的原因,并得出电容值越大滤波效果越好的结论,且电容充放电时间常数大于1秒时,输出电压达到最大值。
The rectifier and filter simulation circuit based on Multisim is designed,it can avoid the inconvenience and potential danger of changing components in the actual circuit,and it can help study the rectifier and filter more thoroughly.By setting up the simulation circuit and adjusting the parameters of relevant devices,the waveform of rectifier filter is presented intuitively,the reason for the difference between voltage and theoretical value after rectifier is analyzed,and the conclusion is drawn that the filter effect is better with the larger capacitor value,and when the capacitor charge-discharge time constant is greater than 1 second,the output voltage reaches the maximum value.
