Abstract: At present, The power supply with redundant parallel structure has become a effective method to increase its capacity,reliability and reduce cost. The paper discussed principles and traits of commonly-used redundancy structure and parallel current sharing, and introduced a design of redundancy parallel current sharing structure that output voltage can be adjusted based on integrated buck chip LM2576 and microcontroller MSP430.

Key words: Switching power supply, Parallel current sharing, Redundant system, Microcontroller
