| Abstract: | This paper introduced a design method of intelligent switching power supply. Information exchange in this design was based on fieldbus communication protocol. C8051F410 SOC was designed as the master control unit. Switching power transforming unit was controlled by DAC which lied in the C8051F410 SOC. In this way, steady voltage output and automatic load current distribution could be finally realized. This paper not only analyzed the circuit design principles and software design process was provided. Power supply controlled in the way of intelligence and digitalization had the ability to realize input-output isolation and automatic load current distribution in parallel circuit. |
