摘　　要：冗余电源技术不仅可以提高电源系统的容量,还能提高系统的可靠性。本文对传统冗余电源的方案和新型的代替方案进行了介绍,并分析了他们的优缺点。着重介绍了MAX8536在冗余电源技术中的工作原理,根据其典型应用电路进行设计与实验,实验结果表明在减小损耗,散热,隔离等问题上取得了明显的改善。Redundancy power supply can not only enhance system capacity, but also improve system reliability. Traditional scheme and novel scheme are introduced in this paper, and both of the advantages and disadvantages are analyzed. The principle of MAX8536 in redundancy power supply is emphasized. It is designed and tested through a typical application circuit, and test results show that the power and heat dissipation, fault isolation are obviously improved in redundancy power supply.
