  • Direct ac-ac converter
  • The direct ac-ac converter is a practical circuit topology for high-efficient power conversion in induction heating(IH) and wireless power transfer (WPT) applications. The conventional Pulse Frequency Modulation (PFM) based power control scheme causes audible noises between the adjacent loads, which operate at different switching frequencies. As a solution for the technical issue, a new fixed-frequency power control methodology for a single-phase direct ac-ac converter is proposed in this research, featuring a wide range of soft switching operations and robustness for abnormal load conditions.
