This paper proposes an FPGA-based emulator of the series resonant half-bridge inverter for measuring the inverter efficiency and detecting hard-switching conditions. The proposed emulator is able to compute the converter operating conditions and efficiency each mains half-cycle, providing useful information for the control unit. Besides, it is designed taking advantage of recent advances in high level synthesis tools, which provides an optimized and straight-forward implementation. The proposed emulator has been applied to an induction heating appliance as an example of efficient and environmentallyfriendly appliances with a major economic and social impact. The obtained results are compared with classical off-line simulation and experimental measurements, proving that the proposed emulator achieves the required accuracy for the induction heating application. As a consequence, the proposed system can be used for improving the system safety and optimizing the converter efficiency and reliability.Index Terms-FPGAs, hardware in the loop, high-level synthesis, digital control, resonant power conversion, induction heating.
