This article describes an intelligent switching power supply design. This switching power supply bases on push-pull mode, and it can work in multiple parallel mode. Besides, it can also automatically adjust according to the proportion of current distribution setting. To achieve the functionality of input-output isolation and automatic load distribution,we make use of intelligent and digital control method. The parallel power system uses Fieldbus mode to information exchange, C8051F410 chip on each module as the core. DAC as the actuator to control switching power conversion unit. When all those units work, this switching power supply can realize stable voltage output and automatic load distribution. The article also gives the power module's software process through analysis the circuits in the end, we have conducted Compliance test for the switching power supply designed.
