Experimental Verification of Sensor-less Coil Position Control System and its Gap Deviation Tolerance Improvement Method in Wireless Power Transmission System of Electrical Trains

摘要

Based on coil-misalignment information detected form position sensor-less method using magnetic coupling information between primary and secondary coils proposed in our previous publication. We built a test-bench for on-board coil positioning for static wireless power transmission in railway application. A method to improve tolerance to gap deviation of positioning has also be proposed. Performance of both positioning and gap deviation tolerance improving have been experimentally verified.
