Abstract

With the in-depth applications of wireless power transmission technology, different application scenarios have different requirements on the output mode, energy efficiency characteristics, and disturbance resistance of the topology. The choice of compensation circuit structure will directly determine the practicality, stability and reliability of power transmission in engineering applications that require stable current or voltage output, adaptation to different load conditions, and ensuring stable system operation. This research systematically compares the output characteristics, power transfer efficiency, and system stability of two wireless energy transmission topologies, S-S type and LCC-S type. The characteristics of two structures are scrutinized through mathematical modeling and simulation experiment analysis. The results show the S-S compensated topology is able to maintain a stable constant-current output state with a maximum efficiency of 96.32% in the 5-10Ωload interval, while the LCC-S topology maintains a constant-voltage output characteristic with a maximum efficiency of 91.55% in the same test range. Research further reveals that the S-S structure has an advantage in terms of power density, but the LCC-S structure exhibits better stability under the mutual inductance change condition. Preferred strategies for both topologies are proposed for a wide range of domains in conjunction with the requirements of specific application scenarios.
