分析二极管半波整流电容滤波电路中的电压波形,利用matlab数值分析方法计算出输出电压到达最大值后下降的波形,时间常数在工程范围取值内,电压输出波形将按照指数曲线规律下降;只有在时间常数很小的情况下,电压输出波形才出现短时间的正弦规律下降曲线,然后再按指数曲线规律下降. 同时用仿真软件与实验平台证实了该结论的正确性.

The voltage waveform of half-wave rectifier and filter circuit has been analyzed. Using Matlab nu-merical analysis,the output voltage waveform can be calculated after the output voltage maximum. If the time constant is in the works scope,the output voltage waveform will Decline in accordance with the index curve. Only when the time constant is very small,the output voltage waveform can decline according to the sine curve in a short time. The correctness of the conclusion was verified by simulation and experiment.
