人力发电装置中负荷调节电路的设计与研究

Design and Research of Load Regulation Circuit in Human Power Generation Device

伴随着全球能源的不断减少和新型便携式电子设备的迅速发展,越来越多的研究者尝试制作各种从环境中采集能量的装置,尤其是一些便携式的人体发电装置。但这些装置往往会给使用者带来额外的运动负担,这种不灵活性严重限制了人体发电装置的市场发展。针对这种发电装置的局限性,设计和制作了一个应用在人力发电装置中的负荷调节电路。该设计是通过单片机采集外部信息后发出一组不同占空比的矩形脉冲来控制人力发电装置负载电路的闭合状态,进而调节发电装置对使用者所产生的负荷。该调节电路可以根据发电装置使用者不同的体力状态来调整发电装置所产生的负荷和发电量,以减轻使用者的负担。在不同的条件下,对该发电装置所产生的力矩进行了测试。实验结果表明,该装置可以调节发电装置所产生负荷的大小。

With the decrease of global energy and the rapid development of a new type of portable electronic devices, there are more and more research about all kinds of devices to collect harvest energy from environment,especially the portable human power generation device. But these devices tend to bring extra movement burden to users and such inflexibility seriously limits its market development. Aiming at the limitation of the power generation device, a load regulation circuit used in a human power generation device is designed and made. The design controls the status of the load circuit by a group of different duty cycle rectangular pulse which is sent by SCM after acquiring the external information. The status will help power generation device to adjust user＇ s load. Different physical status of user will correspond to different loads and generating capacities of power generation device. In this way, users will feel more comfortable. An ex- periment which tests the torque generated by the power generating unit in different conditions proves the device＇ s ability of adjusting user＇ s load.
