A capacitive coupler with asymmetric insulating layers includes a coupler transmitting side and a coupler receiving side. The coupler transmitting side includes a first insulating cavity, and a first plate and a second plate that are arranged on a first plane. The first insulating cavity is configured to enclose the first plate and the second plate with an insulating material. The coupler receiving side is arranged opposite to the coupler transmitting side and includes a second insulating cavity, a third plate and a fourth plate that are arranged on a second plane. The second insulating cavity is configured to enclose the third plate and the fourth plate with an insulating material. The first insulating cavity and the second insulating cavity have asymmetric insulating layers. The capacitive coupler can improve the power transfer efficiency and reduce the safety distance of the electric field.
