Abstract

Pipelines, as important fluid transportation vessels, are extensively used in our modern society. Although numerous nano energy harvesters (EHs) have been reported in recent decades, few focus on developing the pipeline-oriented nanogenerator. This study proposes a mini turbine-based axial-flux permanent-magnet (AFPM) PCB nanogenerator with a bridgeless rectifier for pipeline energy harvesting. Firstly, an AFPM PCB generator with a winding PCB stator is proposed with a compact design to transfer the hydraulic energy to electricity. A designed mini Kaplan turbine blade is used to drive the AFPM PCB nanogenerator. Secondly, an asymmetrical bridgeless AC-DC converter as an interface circuit is proposed without the conventional diode bridge to achieve relatively high power conversion efficiency. Simulations of the PCB nanogenerator and bridgeless converter are conducted by different software to check and optimize relevant designs. Test results indicate that the proposed nanogenerator can steadily output 3.4 W power (power density 4 mW/cm³) and the overall designed EH system can deliver 87 mW of stable output power with its turbine blade driven by a 1.2 m height water reservoir.

带有轴向磁通PCB发生器和非对称无桥电路的管道能量采集器

管道作为重要的流体运输工具，在现代社会中得到了广泛的应用。近几十年来，虽然有许多纳米能量收集器（EHs）被报道，但很少有人关注于开发面向管道的纳米发电机。本研究提出了一种基于涡轮的轴向磁通永磁（AFPM） PCB纳米发电机，该发电机具有用于管道能量收集的无桥整流器。首先，提出了一种具有绕组式PCB定子的AFPM PCB发电机，该发电机设计紧凑，可将水力能转换为电能。设计了一个小型Kaplan涡轮叶片来驱动AFPM PCB纳米发电机。其次，提出了一种不对称无桥式交直流变换器作为接口电路，不采用传统的二极管桥，实现了较高的功率转换效率。利用不同的软件对PCB纳米发生器和无桥变换器进行了仿真，以验证和优化相关设计。试验结果表明，所设计的纳米发电机可稳定输出3.4 W功率（功率密度为4 mW/cm3），在1.2 m高蓄水池驱动下，整个EH系统可稳定输出87 mW功率。
