摘　　要：目前,应用冗余并联结构设计的电源已成为提升供电能力和电源可靠性、降低成本的重要途径。分析了采用冗余结构和并联均流法设计电源的一般方法,并以集成开关降压器LM2576和MSP430单片机为例介绍一种可变电压的冗余并联电源设计方案。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.
