数字电源中的总线技术

由于IT技术对电源技术的不断渗透，数字电源技术应运而生，由于数字电源具有控制灵活、系统结构变化灵活、调节、维护方便和造价低等一系列优点，代表了电源技术的发展方向。而在数字电源中，总线技术发挥了很重要的作用，例如FC、PMBus、SMBus等在数字电源中得到了广泛的应用，并且世界上也成立了相关的论坛和组织，促进了有关总线技术在电源产品中的应用，由于总线技术的引入，极大地提高了电源的工作性能和可维护性，本文主要介绍数字电源中常用的PMBus（电源管理总线）和SMBus（系管理总线）总线技术。

Bus technology used in digital power

With more and more IT technology used in power supply, the digital power comes out. The digital power has such as control easy, the power system＇s construction change easy, adjust and repair easy, the cost is low etc. advantages, the digital power is the power supplies＇ developing direction. The bus technology has play an important roll in the digital power supply, such as the I^2C,PMBus, SMBus etc. have been play an important roll in the digital power supply, in the world many relative technical forum has been found , made the bus technology widely been used in the digital power, greatly improve the power supply＇ s working property and repair property. This paper mainly introduce the PMBus used in digital power supply.
