Abstract

The invention discloses a forwarding and reverse parallel coil design method for inhibiting frequency splitting, and the method comprises the steps: determining the size of a receiving coil according to the size of a charging target in an actual application, and determining the radius and the number of turns of the receiving coil; determining the radius of the forwarding coil and reverse coil of a transmitting end through an excitation source; determining the numbers of turns of the forwarding and reverse coils of the transmitting end according to the flatness of a change curve of mutual inductance between the forwarding and reverse parallel coil of the transmitting end and an unidirectional coil of the receiving coil with the transmission distance, so as to meet the requirements of the optimal transmission adjustment between wireless electric energy transmission systems; carrying out the tuning of a capacitor, and carrying out the tuning of the receiving and transmitting coils to enable the receiving and transmitting coils to work at the used work frequency, thereby achieving the manufacturing. According to the invention, the forwarding and reverse parallel coil of the transmitting end serves as a transmitting coil of a WPT / MRC system, thereby effectively inhibiting the frequency splitting phenomenon of the WPT / MRC.

Description

technical field [0001] The invention belongs to the technical field of wireless energy transmission equipment, and in particular relates to a design method of forward and reverse parallel coils for suppressing frequency splitting. Background technique [0002] With the rapid development of science and technology, a large number of civilian electronic products such as mobile phones, digital cameras, digital music players, etc. appear in people's daily life, bringing a lot of convenience to our life, but there are also many problems Nowadays, the functions of mobile phones have increased, and the implantation of these functions in mobile phones will inevitably increase the power consumption of mobile phones, and the charging devices used by various electronic devices are not common to each other, and the power supply is connected to each other through cables. The matching interface charges the battery. Therefore, in order to overcome the defects of the traditional wired charg...
