Effect Analysis of Multiple Loads Position and Detach of Receiving Coil in Multi-Winding Parallel Two-Wire Wireless Power Transfer
Hideaki Abe WPT2018-34
Abstract (in Japanese) (See Japanese page) 
(in English) Research on wireless power transfer is being conducted from various perspectives. The author has studied the possibility of a new usage in a system using magnetic coupling and studied the free-position power supply system on the line assuming application to detachable wall-mounted power supply and the like. This paper describes on research on constant voltage feed to multiple loads using two parallel wires by multiple windings. Differences from the method used for automatic transport vehicles etc since ancient times are described, and the influence of the placement position and interval of multiple loads and loads on loading and unloading is verified by analysis and trial production. In particular, the constant voltage receiving performance of multiple loads was evaluated in constant voltage driving and constant current driving of the power transmission coil. In the analysis, the secondary equivalent circuit with the coupling coefficient k as a parameter was used to clarify the theoretical viewpoint on the multiple load feeding. As a result of trial verification in the two driving methods, the influence on the received voltage suggested by the analysis was demonstrated.
