摘 要：In order to prolong continuous working time of the mobile robot to inspect on transmission lines,a robotic power management system is introduced in this paper based on the wireless power transmission technology.Magnetic resonance coupled WPT (wireless power transmission) unit is applied and its performance is analyzed in form of electrical circuit mode method.By modeling the output power of WPT unit,the relationship between coupled coefficient,angular frequency and amount of output power is given,and furthermore the energy consumption of each unit in power management system is quantified.Experiment results verified the validity of the circuit model of WPT and showed that the system could work conveniently in wireless way to provide power for the inspection robot.
