摘要

能量收集在微电源应用中越来越受欢迎,在微电源应用中,环境能量被用来为系统供电。为了延长设备的使用寿命,保证系统的正常运行,应最大限度地利用能量换能器采集的电能来供给系统负荷。本文回顾了不同的技术和解决方案,以最大限度地提高收获功率。讨论了不同的环境能源和相应的能量转换器的特性。总结了能量传感器最大功率点的检测与跟踪算法。提出了执行MPP跟踪算法的不同电源管理单元(PMU)设计。

Maximizing the harvested energy for micro-power applications through efficient MPPT and PMU design
Energy harvesting is becoming more and more popular for micro-power applications where the environmental energy is used to power up the systems. In order to prolong the device lifetime and guarantee the system operation, the harvested power from the energy transducer to supply the system load should be maximized. This paper reviews different techniques and solutions to maximize the harvested power. Different environmental energy sources and the characteristics of the corresponding energy transducers are discussed. Algorithms to detect and track the maximum power point (MPP) of the energy transducer are summarized. Different power management unit (PMU) designs to execute MPP tracking (MPPT) algorithms are presented.
