基于Cockcroft-Walton电路的PMT高压电源

摘要

According to the actual needs of distributing and using the resources in laboratorymore reasonably,this paper designed and implemented a PMT high voltage power supply with high efficiency and low ripple.It included:LM 10CLN voltage control part,boost part based on cockcroft-walton,feedback and protection part and Ⅰ-Ⅴ conversion part.Finally,the PCB production is completed.The experimant showed it is feasible,which runs well,the index of linearity and ripple meets the requirements.%根据当前实验室资源的需要合理分配与利用的需求,设计与实现了一种高效率、低纹波的PMT高压电源.该电源主要有LM10CLN电压控制部分,基于Cockcroft-Wahon升压电路部分,反馈和保护电路部分和Ⅰ-Ⅴ转换部分来实现.最后完成电路的PCB板制作,通过对样品的试验,验证了本方案是可行的.电路运行良好,电路的线性度、纹波大小均符合要求.
