| 摘要: |
| 提出球形集能拓扑并建立其数学解析模型，分析影响其集能效果的因素。考虑到集能拓扑的实际应用，在球形拓扑的基础上改进为球冠型拓扑结构。通过建立调理电路的大信号和动态扰动模型，给出了调理电路反馈网络的设计原则，仿真结果验证了电路的可行性。针对外电场变化对调理主电路工作特性的影响，建立了仿真模型，研究了等效输入电压变化下的调理主电路工作特性。在搭建的自供能系统实验平台上进行实验，实验结果验证了集能转换器的整体工作性能。 |

| Abstract: |
| A spherical energy scavenging topology is proposed，its mathematically analytical model is built and its influencing factors are analyzed. For the practical applications，the spherical-cap topology is adopted. The large signal model and dynamic disturbance model of the conditioning circuit are built，the design principle of its feedback network is given，and its feasibility is verified by the simulative results. Since the variation of external electrical field may influence the operating characteristics of main conditioning circuit，a simulation model is built to study its operating characteristics under the equivalent variation of input voltage. An experiment platform of self-power system is established and the overall operating performance of the energy scavenging converter is verified by the experimental results. |
