电容串联分压输出电路特性研究

为减少普通变压器瞬变高电压及电源电流对电路有源器件的冲击，详细介绍了一种电容串联分压输出电路的结构及其工作原理，利用实验的方法给出输入一输出电流与负载的关系及输出电压与负载的关系曲线图，通过关系曲线图对电容串联分压输出电路的特性进行深入的研究，结果表明：该电路没有普通变压器瞬变高电压对电路的冲击，也没有较大的电源电流对电路的冲击，这为初级有源器件的选用带来方便。

Characters on voltage division output circuit of the series capacitor

In order to reduce transient high-voltage impacted in normal transformer and the impact from current,this paper analyzed the structure and the work principle on voltage division output circuit of the series capacitor.Two relationship graphs were drawn with experiment,including input-output current and load,output voltage and load.The characters on voltage division output of series capacitor were researched in detail.The result proved that transient high-voltage impacted circuit in normal transformer,but the circuit didn't.And there isn't the impact from large power current.It is more convenient to select the primary active devices.
