Fpga Implementation Of A Gain-Scheduled Controller For Transient Optimization Of Resonant Converters Applied To Induction Heating

This paper focuses on the optimization of the dynamic behavior of a resonant converter applied to induction heating with highly varying operating conditions. An FPGA-based gain scheduled controller is proposed using the information of the modulation parameters and an on-line impedance identification system. As a result, the proposed controller significantly improves the converter dynamic response, improving the performance and safety operation of the power converter.
