提出了一种应用于集散控制系统的基于功耗自适应技术高精度电流输出模块的低功耗设计方案。当模块输出电流动态变化，负载（阀门）功耗会随之变化，通过调节管的压降反馈给通道电压调节模块的方式调节输出通道驱动电压，使之与负载功耗相匹配，达到内部功耗可控的目的。此方案大大减少了输出电流模块内部多余功耗，实现了低功耗目的，提高了模块内部器件及系统的可靠性。该方案相比常规方案，其对模块的散热要求更低，易于实现高密度集成，应用于手持便携式设备时具有更强的续流能力。

This paper presents a Iow-power soIution for high precision current output moduIe of DCS based on power-adaptive technoIogy.When the Ioad power changes,the driving voItage of output channeIs changes by the way of the adjutage voIt-age feedbackes to the channeI voItage reguIator moduIe.This soIution reduces the internaI redundant power a Iot,achieves the goaI of Iow-power and improves the reIiabiIity of internaI components and system.To compared the conventionaI soIu-tion,it has Iower heat dissipation requirement and it's easier to achieve high density integration.When it is used in handIed devices,it has a stronger freewheeIing capabiIity.
