本文提出一种用于室内光伏能量收集的电感式升压转换器，支持5µW至10mW的宽输入功率范围，并集成了最大功率点跟踪功能。解决了室内光照变化大、太阳能电池输出功率范围宽导致的能量管理困难问题。
Energy harvesting provides a means to supply wireless sensor networks in building environments with autonomous and sustainable power [1,2]. Indoor light can be converted into electricity by a solar cell and stored in a rechargeable battery or super-capacitor [3]. Depending on the indoor illumination level and the installed location as well as the orientation of the solar cell, the output power of an amorphous silicon solar cell can vary from less than a few µW/cm² up to hundreds of µW/cm² [3]. To manage the variation in both the illumination and panel size, a power-management circuit that is able to efficiently handle a wide range of input power is necessary. A solar cell can be modeled as a light-controlled current source in parallel with a diode. Its output current is determined
