AI Technical Summary
In existing contactless energy transfer systems, the primary current has high fluctuations, which leads to the need for complex current smoothing devices, increasing structural space, weight and cost, while also resulting in significant undesirable electromagnetic far-field effects.
By employing multiple converters and primary coils, phase-shifting technology is used to ensure that the primary currents have the same frequency and are phase-shifted with each other, reducing the fluctuation of the primary current. Low-fluctuation current transmission is achieved through the mutual coupling of the converter and the secondary coil.
It reduces structural space, weight, and cost, minimizes electromagnetic far-field effects, and enables efficient charging of batteries for mobile power-consuming devices.
