Research on key technologies of magnetic resonance wireless power transmission for inspection robot

In order to prolong continuous working time of one inspection robot for power transmission lines, a robotic power station based on wireless power transmission technology is introduced in this paper. Model equations of magnetic coupling transferring is founded, and the condition under which the system can transfer power at the maximum efficient is detailed by analizing the coupling relationship between parameters as working frequency, coupling efficient, and operating range. At last, experiments was introduced to verify the correctness of the analysis of the above theory.
