Abstract

A standard home in the United States has access to the 120V AC power for use with home appliances. However, many home electronics are powered by DC electricity. This introduces energy loss in the conversion process. A residential DC electrical system will avoid such conversion loss by storing energy in batteries and supplying it to DC appliances. Unfortunately, there is no existing voltage standards for DC appliances, which makes it challenging to power DC appliances straight from a DC wall outlet. The Smart DC Wall outlet addresses this by automatically adjusting its output voltage to meet any required DC load voltage. A solution involving low-voltage detection algorithm within a DC-DC converter is presented in this paper. The proposed solution monitors trends in the output current and sets the output voltage accordingly. Simulation tests resulted in identification of the required output voltage of five out of seven test devices. Results also indicate the possibility of generalizing the turn on characteristics of DC devices with more refined algorithm to improve successful voltage identification by the Smart Wall outlet.

智能直流墙壁插座与负载电压检测

在美国，一个标准的家庭可以使用120V的交流电源来使用家用电器。然而，许多家用电器是由直流电供电的。这在转换过程中引入了能量损失。住宅直流电力系统将通过将能量储存在电池中并将其供应给直流电器来避免这种转换损失。不幸的是，没有现有的直流电器电压标准，这使得直接从直流墙壁插座供电直流电器具有挑战性。智能直流墙插座通过自动调整输出电压以满足任何所需的直流负载电压来解决这个问题。本文提出了一种涉及DC-DC变换器低压检测算法的解决方案。提出的解决方案监测输出电流的趋势，并相应地设置输出电压。模拟试验确定了七个试验装置中五个所需的输出电压。结果还表明，可以通过更精细的算法来推广直流器件的导通特性，从而提高智能墙插座的电压识别成功率。
