| Abstract: | Energy scavenging converter converts electric field energy to power,which is the principal element of smart monitoring unit for on-site self-powering. The finite element method is used to build the model of the plate-type energy scavenging converter,the impacts of its structural parameters on conversion performance are analyzed,and its adaptability to the change of electric field is discussed. A topological design of spherical energy scavenging converter is proposed and modeled,and the simulative results show that,it is better than plate-type one in output voltage,induced charge and inner electric field distribution,suitable for more complicated and severe electromagnetic environment. |
