中文摘要:
      无线电能传输系统在运行过程中可能会遇到母线接地、开路、元器件损坏等各种故障情况。分析了故障情况下原边母线电流电压、副边母线电流电压与故障原因的特征关系,搭建了3kW无线电能传输系统仿真电路,建立了各种故障的比较规则,提出了将该故障特征用于无线充电系统的在线故障识别方法。分析表明,利用该方法可以有效判断系统故障位置,增强系统保护。
英文摘要:
      In the course of operation, the wireless charging system may encounter various special conditions such as Busbar grounding, open circuit and component damage. The relationship between the current-voltage of the original-auxiliary side bus and the cause of the fault is analyzed under the condition of the fault, and the simulation circuit of the 3kW wireless charging system is built, the comparison rules of various faults are established, and the on-line fault recognition is realized. The analysis shows that this method can effectively judge the fault location and enhance the system protection.
