Analysis of efficiency characteristics of compensation topology structure in magnetic coupled resonance wireless power transfer

  • Received Date: 2021-02-15
  • Four resonance compensation topologies equivalent circuit models for magnetic field coupling resonance wireless power transfer system (primary side series and secondary side series type,primary side series secondary side parallel type,primary side parallel secondary side series type and primary side parallel secondary side parallel type) was constructed. The efficiency characteristics of magnetic field coupling resonance wireless power transfer systemwasanalyzed. The influence of coupling coefficient and quality factor on system efficiency was studied. The simulation results showed that the secondary side resonance compensation topology had a greater impact on the system efficiency,and the system efficiency was more sensitive to changes in the coupling coefficient and quality factors.Compared with the secondary side using the series compensation topology,the system had a wider range of high transfer efficiency when the secondary side used the parallel compensation topology. The experimental results verified the correctness of the simulation results.
