Magnetically coupled wireless energy transmission systems are based on magnetic field coupling for energy transmission. In magnetically coupled wireless energy transmission systems, a constant current input to the transmitter side of dynamic wireless charging avoids excessive primary-side currents due to mutual inductance fluctuations when the transmitter coils are compensated in series. In this paper, we propose a Dual-Mode WPT System with Constant Current Transmitter in Dynamic Mode and Triple-Coil in Static Mode for dynamic wireless charging transmitter constant current and improving the efficiency and transmission distance of static wireless charging system. The system enables constant current input at the transmitter side during dynamic wireless charging to prevent excessive primary-side current, while improving static wireless charging efficiency and transmission distance as well as reducing device current stress.
