Design of Redundant Parallel Power Supply Based on Integrated DC/DC Modules
Taking into account the efficiency, cost-effectiveness and reliability of power supply, redundant parallel power supply controlled by microcontroller could be a good solution for us. This paper analyzes principles and traits of parallel current sharing structure. Then a design of redundancy parallel current sharing structure is introduced, which is based on integrated buck chip LM2678 and microcontroller MSP430. The design has good fault-tolerant ability, and its output voltage can be adjusted easily. The capability and feasibility of this design has been verified by the simulation and experiment.
