摘　　要：文章针对有关文献采用以锯齿波电压代替半波整流电容滤波电路输出电压原本波形的方法,分析计算通过半波整流二极管中的电流,文章指出假设的锯齿波违反电路基本定理和能量守恒定律,其计算结果根本不是原电路的真实情况。文章采用另一种近似分析方法,即以指数波代替原来的输出电压波形,推导出了计算半波整流二极管中的电流公式,且经过实际计算结果证明了该公式的正确性。The current through the diode of a half-wave rectifier can be approximately calculated by the sawtooth wave voltage,but mistakes often appear in the approximate calculation.In one paper on this issue,the analysis on the sawtooth wave used by the author disobeys the basic principle and the law of energy conservation,thus the calculation result does not conform to the real situation of the circuit.Accordingly,a correct calculation is given by the author of this paper.
