Analysis and Design of 6.78M WPT Architecture for Configurable Power Applications Based on DCX Energy Synthesis and Functional Execution

Improving the power level of high-frequency wireless power transfer (WPT) is important research. In this process, how to make the system have high-efficiency energy conversion, strong robustness, and power adjustment capabilities is a key technical difficulty. In this letter, a configurable WPT system architecture with multiple fixed energy state (DCX) channels combined with functional execution (FTE) channels is proposed. With the cooperation of the FTE branch, the state of the DCX branch is effectively locked so as to complete the ultimate efficiency optimization. The flexible adjustment of the power level is realized through the configurable combination of DCX branches. Meanwhile, the robustness improvement and power fluctuation of the system are undertaken by the FTE branch, and the constant output is also supported. Furthermore, a 178-W experimental prototype was built, and the overall efficiency reached 93.64%.
