Design and Development of Wireless Power Transfer System for AUV Applications

Abstract

Wireless power transfer (WPT) in air has been a research topic over a century and has been extensively used in applications such as electric vehicles (EV’s), mobile devices and RF identification (RFID) etc. Research of WPT in under water applications is more of interest because of attenuation to fields from water due to its salinity and water currents. In this paper a 1KW wireless power is transferred for autonomous under water vehicles (AUV’S) for charging the AUV battery. The eddy currents in water and their losses are considered for performance calculations. Simulation tools such as Ansys maxwell and LT spice is used for coil and circuit analysis respectively.
