- Abstract
- In this paper, the influence of the electromagnetic wave caused by lightning on the magnetic resonance wireless power transmission system is analyzed. The intrusion process of the electromagnetic wave to the wireless power transmission system is implemented to an integrated circuit model based on relevant researches on the generation and the propagation of the electromagnetic wave by lightning. The integrated circuit model is simulated assuming that the magnitude of the electric field of the electromagnetic wave is 3000kV/m and the electromagnetic wave travels 20m and intrudes to the wireless power transmission system. As a wireless power transmission system, two-coil system and four coil system is used in the simulation. The frequency of both wireless transmission systems is set to 60kHz. The double exponential waveform with 1.2/50μs is selected as a lightning impulse. As a result, the voltage of 9.06kV is induced to the two-coil system, and the voltage of 3.96kV is induced to the four-coil system when the lighting causes the electromagnetic wave near the wireless power transmission system.
