摘要
本文对整流电路建立非线性微分方程,并根据其稳定解的周期性,推导出电路的电荷量守恒方程。通过一些假设条件对方程进行近似和简化,分别对脉冲波、三角波、余弦波三种波形作为输入电压信号进行分析,得到其近似解,与其它资料或实验结果完全一致。最后,指出本分析方法尚存在不足之处,以便对整流电路得到更全面的分析和认识。
In this paper, the non - linear equation for voltage commutation circuit was established, and the conservation electric - charge equation was worked out basing on the periodicity of its stable solution. The approximate equation was simplified under conditions of some hypothesis. The solutions were gotten when the input voltage signals were the cosine - wave, the pulse - wave and the trigonometric - wave respectively that are identical with others reference or the experiment results. At last, the shortcoming of the method was pointed out so that the voltage commutation circuit is understood and analyzed all around.
