Research on reliability of Magnetic Resonance Wireless Charging
Electric vehicles of magnetic resonance wireless charging have been put into use in some areas, and gradually gaining in popularity.For its security and reliability must be both guaranteed, reliability analysis should be implemented.The definition and operating principles of wireless power transmission are given in this paper.Analysis of several topology wireless charging circuit stage.Focuses on magnetic resonance wireless charging technology for electric vehicles in terms of energy supply, the reliability analysis of circuit element and the external environment interference has been done, and generate reports.The reports show that: When considering the reliability of the high-frequency inverter circuit alone, using the general level of circuit elements that can make the whole circuit system to work around 7 years.Face to the change of power frequency, transmission distance, load size, magnetic resonance wireless charging can better meet the needs of wireless charging for electric vehicles.
