| Popis: | Autonomous underwater vehicle (AUV) is a key mobile node in the ocean observation network. However, the limited endurance capacity and limited cruising range have become the bottlenecks in the wide application of the AUVs. In order to extend cruising range, this paper develops a uniform power inductive power transfer (IPT) system for AUVs. A novel magnetic coupler with a low output fluctuation, low weight of receiver and a low space occupation of the AUV is proposed in this paper. The proposed magnetic structure employing a quadruple-coil transmitter and a crossed dipole receiver utilizes uniform horizontal magnetic flux to establish stable coupling against rotational and axial misalignment. An IPT circuit topology is designed and analyzed in detail, meanwhile, the phase difference of the excitation currents is optimized to achieve the power and efficiency stability versus misalignments. The proposal is analyzed, established, and tested in this paper. The magnetic receiver weighs only 414 g. The results show that the prototype can deliver 964.7 W with a DC-DC efficiency of 90.9%. In the process of rolling dislocation from -20 to 20 and axial dislocation from -30 mm to 30 mm, the maximum fluctuation of output power is 12.1% and 20.2%, respectively. |
