【摘 要】

High voltage gain is required in many practical wireless power transfer(WPT) systems and the robustness of voltage is very important for wireless power transfer systems with high voltage gain. This work proposes a method to select the optimal topology with good performances in three aspects: robustness, voltage gain and transfer efficiency for several common topologies of WPT system and optimize the parameters. By comparing common topologies, it is found that the LCC-P topology can guarantee good robustness under the condition of low coupling when the voltage gain of system is more than 2. Experiment demonstrates the performance of systems using LCC-P topology.
