| A DSP based intelligent precise stabilized current power supply is designed to improve the precision and stability of the power supply. This paper introduces the constitution and control method of the precise stabilized current power supply. Stabilized current control is realized through DSP to achieve stable and precise output current as well as over current and over voltage protection function to improve the performance of the power supply. The results of emulation and experiment verify that this system, characterized through simple circuit, easy adjustment, high control accuracy, good stability and low ripple factor, is specially suitable for applications of high precision. |
