Aiming at the problem of decrease in efficiency due to misalignment of wireless power transfer (WPT) coil, a novel coil with high misalignment tolerance was proposed. First, the factors that affect the efficiency and the method of improving the efficiency and misalignment tolerance of the coil are a...
