A Direct AC–AC Converter for Inductive Power-Transfer Systems

  title={A Direct AC–AC Converter for Inductive Power-Transfer Systems},
  author={Hao Li and A. P. Hu and G. A. Covic},
  journal={IEEE Transactions on Power Electronics},
This paper proposes a direct ac-ac converter to generate a high-frequency current for inductive power-transfer (IPT) systems. Unlike traditional dc-ac converters for IPT systems, the proposed converter can achieve a high-frequency current generation directly from an ac power source without a dc link. The power converter can maintain high-frequency resonance by natural circuit oscillation and discrete energy injection control. A variable-frequency control strategy is developed to vary the… CONTINUE READING
