摩擦纳米发电机(triboelectric nanogenerator, TENG)作为低频微弱机械能收集的前沿技术,凭借高瞬时功率密度和环境兼容性在能量采集和自供电传感领域备受关注。然而,传统交流型TENG的高开路电压、低短路电流及输出相位失配特性严重制约其能量利用。针对这一技术瓶颈,开发高效的电源管理策略,尤其是高集成度专用集成电路显得尤为重要。本文综述了TENG电源管理策略的研究进展,重点剖析了整流技术、开关控制以及集成电路设计在能量转换效率提升中的作用,总结了高效能量管理策略的设计原则与优化路径,为推进TENG在分布式能源系统中的实用化提供理论支撑和技术参考。
Abstract:As a cutting-edge technology for low-frequency weak mechanical energy harvesting, triboelectric nanogenerator(TENG) has attracted much attention in the field of energy harvesting and self-powered sensing due to its high instantaneous power density and environmental compatibility. However, the high open-circuit voltage, low short-circuit current and output phase mismatch characteristics of traditional AC TENG seriously restrict its energy utilization. In response to this technical bottleneck, it is necessary to develop efficient power management strategies, especially highly integrated dedicated integrated circuits.This paper summarizes the research progress of TENG power management strategy, focuses on the analysis of the role of rectification, switch control and integrated circuit design in the improvement of energy conversion efficiency, and summarizes the design principles and optimization paths of efficient energy management strategy, which provides theoretical support and technical reference for promoting the practical application of TENG in distributed energy system.
