“…In the paper [221] ,author proposed to reduce the volume and cost for a semi bridgeless active rectifier (SBAR) with a variable frequency impedance tuning control. Just applying the fixed frequency control in EV application is not enough, because of the large aluminum shield and the wide range of the misalignment cause a large impedance mismatch.…”

“…To decrease the quantity and costs of a semi bridgeless type active rectifier (SBAR), the study's researcher 104 advised utilizing a variable speed resistance adjusting controller. Due to the enormous metal shield, as well as the broad selection of misalignment, a maximum impedance value incompatibility is generated in an EV application, therefore using fixed frequency management is unsuitable.…”

“…However, it requires an additional circuit at the secondary side installed under the chassis of the electric vehicle, which increases the weight and cost of electric vehicles. The secondary side control to address the misalignment can be realized by controlling the rectifier [30] or controlling the additional dc-dc converter at the secondary side [31]. Dualside control is a control scheme that controls both sides at the same time, which increases the complexity.…”

A novel autonomous self-aligning wireless power transfer system is proposed to address the issue of misalignment in the stationary wireless charging of electric vehicles. Misalignment between transmitter and receiver is the biggest obstacle in the charging process of wireless charging of electric vehicles that hampered the widescale adoption of this technology. To improve the misalignment performance, a moveable transmitter is proposed, in which the transmitter pad is mounted on a robot. The robot is equipped with a magnetic field sensor located at the center of the circular transmitter pad. Employing the proposed algorithm, the transmitter's coil mounted on the robot follows the receiver based on measuring the magnetic field. In this case, by having misalignment, the robot moves the transmitter pad to remove misalignment and create alignment. For validating the proposed self-aligning mechanism, an experiment test has been done, and the experimental results show the effectiveness of the proposed mechanism in aligning the transmitter pad with the receiver pad. The design process and implementation of the robot by considering the transmitter's coil weight and the required torque to move the transmitter's coil are detailed.
