能量采集系统，如自供电无线传感器节点，在其不断变化的环境中依赖于一组不同的能源来提供能量。为了应对环境条件的巨大变化，需要一种高度灵活的多电源电源。本文描述了一种用于多台能量收集机的集成电源管理系统，该系统采用了能量感知和充电回收。以前的多输入电源管理系统一次只允许从一个电源[1](通常是电压最大的电源)获取能量，从而浪费了来自其他能量采集器的能量。为了增加可用的总能量，这里介绍的工作允许系统同时收集和添加来自多个源的电压。
Energy harvesting systems such as self-powered wireless sensor nodes rely on a diverse set of energy sources in their continuously changing environment for power. A highly flexible power supply with multiple sources is needed to deal with large variation in environmental conditions. This paper describes an integrated power management system for use with multiple energy harvesters, which employs energy awareness and charge recycling. Previous multiple-input power management systems only allow energy to be harvested from a single source at a time [1] (typically the source with the largest voltage) thereby wasting the energy from the other energy harvesters. In order to increase the total energy available, the work presented here allows the system to gather and add together voltages from multiple sources at the same time.
