Development of the Wireless Power Transfer Technology for a Sliding Door

The sliding door’s movement is 3-dimensional unlike the conventional door. So the electric power and signal are exchanged via the long ‘Power Cable’. It has a quite complex structure in order to be suitable to connect the vehicle’s body and the sliding door even during it’s moving. As the result, it is more expensive than conventional door’s one and the quality could not be guaranteed easily. In this paper, I have developed new technology which could transfer electric power by ‘wireless transfer’ in order to resolve the problem from using ‘Power cable’. I would propose the proper structure to transfer the electric power at any position of the sliding door without any physical connection. To transfer the electric power which drives the window regulator and the actuators in door, I have applied the ‘inductive coupling’ system. And in order to decide the engineering properties - such as the dimensions of the core, the values of the electric elements and the frequency of the transferred electricity - a myriad of computer analysis and experiments under various conditions would be implemented. Finally, the optimal solution was figured out and it was validated under the real vehicle’s condition. This research would be adopted in various types of the future door system.
