信息终端的关机“零”功耗设计方案与应用

Design and Application of Zero Power Consumption for Information Terminal Shutdown

常用智能终端及家电设备,如PAD、电视机、机顶盒等,通常都存在一定的关机功耗,如PC机、电视机关机功耗可达数瓦,小一些的智能终端也达数百数十毫瓦。常年累月,白白浪费掉的能源不可估量。本文介绍设计一种待机微功耗电路设计与应用,解决通常关机待机功耗问题,且具有通用性,是目前实现节能减排增效的一种有效技术手段。

The often-used smart terminals and home appliances including PAD, TV and set-top box have off-state power consumption. For example, the power dissipation at shutdown for PC and TV may reach several watts, and this figure is approximate hundreds or tens of milliwatts for small smart terminals. The wasted energy for years is immeasurable. This paper gives the design and application of an ultra-low power standby circuit, which can solve the problem of power consumption in standby and off-state. It is a common and effective technical means for energy saving and emission reduction.
