摘要: 为解决大功率LED在复杂环境中的供电间断与振动干扰等问题，本文构建了一种紧凑型光伏(PV)、热电(TEG)与压电(PZT)多源混合能量收集系统。该系统通过分级能源管理实现多源输入的融合与调度，并采用瞬态电压辅助电路完成冷启动。同时，三种能量源互补协同，可支撑不同天气条件下的全天候运行。实验结果表明，相较传统架构，所提混合结构的自启动时间与稳定输出建立时间分别降至4 s与15 s，降幅分别达到76.47%与85%。该方案为大功率LED照明提供了一种高效且可行的自供电技术路径。
Abstract: To address intermittent power supply and vibration disturbances affecting high-power LEDs in complex environments, a compact multi-source hybrid energy-harvesting system integrating photovoltaic (PV), thermoelectric (TEG), and piezoelectric (PZT) sources is developed in this study. Multi-source inputs are integrated and coordinated through a hierarchical energy-management scheme, and cold start is enabled by a transient-voltage-assisted circuit. Complementary operation among the three energy sources is leveraged, and all-weather power generation under varying meteorological conditions is supported. Experimental results show the proposed hybrid structure reduces self-starting and stable output establishment times to 4 s and 15 s. This represents significant decreases of 76.47% and 85% compared to traditional architecture. An efficient and practical self-powered technical route is thus provided for high-power LED lighting.
