摘要

本文提出了一种能量收集系统,以减少飞机内电缆的质量,重点是开发一种能量转换链,从数据线收集能量,最终用于为飞机传感器或无线监控供电。该接口在不干扰数据传输的情况下从数据CAN总线获取能量,在完全集成的ldo输出端提供高达60 mA的输出电流和1.65 V的输出电压,在充电泵输出端提供5.035 V的输出电压,在不到5 ms的极短的稳定时间内和158.2 mV的低电压纹波,以便为飞机传感器供电。最常见的能量收集源是太阳能电池、风力涡轮机、振动能和热电发电机。能量收集链(EHC)不依赖于环境,由基于集成具有快速瞬态响应的全集成ldo的快速模拟设备组成,以使飞机传感器自供电并实时运行。采用0.18 μm CMOS工艺设计了采集系统,仿真结果证明了该结构的优越性。

Improving latency time of an energy harvesting chain by implementing a fully-integrated-LDO for aircraft WSN
This paper presents an energy harvesting system to reduce the mass of the cables within an aircraft, focusing on the development of a power conversion chain to harvest energy from data lines, which is eventually used to supply the aircraft sensors or wireless monitoring. This proposed interface harvests energy from data CAN bus without disturbing the data transmission, providing an output current up to 60 mA and an output voltage of 1.65 V at the output of the fully-integrated-LDO and an output voltage of 5.035 V at the output of the charge pump within a very short settling time of less than 5 ms and a low voltage ripple of 158.2 mV, in order to feed the aircraft sensors. The most common energy harvester sources are solar cells, wind turbines, vibration energy and thermoelectric generators. The energy harvesting chain (EHC), which does not depend on the environment, is composed by fast analogue devices that are based on integrating a fully-integrated-LDO with a fast transient response, in order to make the aircraft sensors self-powered and operate in real time. The harvesting system is designed in 0.18 μm CMOS technology, the simulation results prove the advantage of the proposed architecture.

期刊介绍: IJPT addresses novel scientific/technological results contributing to advancing powertrain technology, from components/subsystems to system integration/controls. Focus is primarily but not exclusively on ground vehicle applications. IJPT''s perspective is largely inspired by the fact that many innovations in powertrain advancement are only possible due to synergies between mechanical design, mechanisms, mechatronics, controls, networking system integration, etc. The science behind these is characterised by physical phenomena across the range of physics (multiphysics) and scale of motion (multiscale) governing the behaviour of components/subsystems.
