摘　　要：为提高微能量收集的转换效率,分析了3种典型的换能装置结构及其等效电路,探究了3种换能装置的能量收集电路的工作原理、优缺点及能量转换效率,对比分析了常用储能器件.结果表明:带控制单元的能量收集电路效率高,超级电容和锂电池适合微能量收集系统.基于以上分析,对微能量收集技术和储能器件研究提出了建议,带控制单元的能量收集电路和组合形式的储能系统是进一步研究微能量收集系统效率的一个方向.In order to improve the conversion efficiency of micro energy harvesting, three typical generators were studied and their equivalent circuits were analyzed. The working principles, advantages and disadvantages and energy conversion efficiency of three energy harvesting devices were discussed. Typical energy storage devices were compared. The results showed that the energy harvesting circuit with control unit was the most ef- fective one, supercapacitor and lithium battery were suitable for micro energy harvesting system. Based on the analyses, some advises were proposed for the micro energy harvesting technology and energy storage devices. Combining the energy harvesting circuits with control unit and combined form of energy storage system would be one of the directions for further research on the efficiency of micro energy harvesting system.
