Abstract

In order to achieve more efficient and effective transferred power, the coupled structure of an undersea power transmission (CPT) system was carefully designed. The coupling magnetic field was analyzed by FEM simulation to reveal the transferring nature of two coupled windings. Simulation and prototype measurement were compared to demonstrate that the optimal winding layout has higher coupling coefficient. Furthermore, high frequency current in windings was also being considered in the optimization to calculate power loss. In this calculation, alternating current resistance was serious discussed because it plays a more important role in power loss than direct current resistance in windings does. Optimizing methods mentioned in this paper are very useful in system design to obtain a capable coupled structure, especially those works in undersea environment.
