Keywords: Inductive heating, variable capacitor, MPPT
AbstractConsidering the increasing use of induction heating, this study sought to adapt a maximum power point tracking technique already used in photovoltaic systems to deliver the best efficiency to the load, even in situations where the characteristics or parameters change. In conjunction with the tracking algorithm, the variable capacitor technique was implemented, which activates an auxiliary switch by varying the capacitance value keeping the system in resonance. To obtain the results, the system was tested with fixed capacitance values and with the action of the algorithm. In response, the system behaved satisfactorily, validating the hypothesis of better heating performance when submitted to the tracking algorithm.
