N2 - This article proposes and implements a multi-topological low-frequency-switching (LFS) high-frequency-resonating (HFR) wireless power transfer (WPT) system, which can significantly improve the system efficiency and fluctuations for specific HFR-WPT applications at equal power level. To adjust the HFR wireless power, high-frequency-switching phase-shift control (PSC) will increase the switching loss and operating temperature, thus inevitably degrading the system efficiency and stability. With the system optimization for suppressing current fluctuations, an LFS-PSC technology is deeply investigated to control wireless power while reducing the switching and conduction losses. Also, it can effectively mitigate the adverse impacts of dead zones on the power and efficiency losses. The system efficiencies using two exemplified WPT topologies can reach 89.53% and 91.62%, while they can be improved by 2.75% and 2.13% during power control. The theoretical analysis, simulation, and experimentation are given to verify the feasibility of the proposed systems using LFS-PSC.
