基于开关型集成稳压芯片的数控恒流源

Digital constant current source based on integrated switch chip

针对数控直流恒流源的设计进行了探讨,重点介绍一种高效率的基于电压可调开关型集成稳压芯片的数控恒流源。就整机工作原理、相关参数计算做了详细介绍。系统具有输出电流可预置,输出纹波电流低等特性。

The design of DC constant current source was discussed in this paper; an efficient digital controlled constant current source based on integrated switch chip with adjustable output voltage was mainly introduced. The principle of the system and the relation parameter was introduced in detail. This system has the functions of current preset, low current ripple, and etc.
