摘　　要：随着物联网技术和无线传感技术的快速发展,低功耗设备的自供能技术得到了广泛研究和关注。针对传统微能量收集系统存在的电路结构复杂、效率低、电压传输比受限等问题,提出了双级Boost变换器微能量存储方案,并与传统单级Boost升压方案进行了对比分析。通过Matlab仿真进行理论验证,结果表明,双级Boost变换器微能量收集方式极大地提高了同等电压高变比传输下的效率,使设备的组网供能更易于实现,为低电压微能量收集系统的设计提供了一种新方案。With the rapid development of Internet of things technology and wireless sensor technology,the self powered technology of low-power equipment has been widely studied and concerned. Aiming at the problems of complex circuit structure,low efficiency and limited voltage transfer ratio existing in traditional micro energy collection system,a micro energy storage scheme of two-stage boost converter is proposed and compared with the traditional single-stage boost boost scheme. Through the Matlab simulation,the results show that the two-stage boost converter micro energy collection mode greatly improves the efficiency of the same voltage high ratio transmission,makes the networking energy supply of equipment easier to achieve,and provides a new scheme for the design of low voltage micro energy collection system.
