This paper presents the fuzzy logic controller based power semiconductors switching of an energy efficient induction heating system. In induction cooking system, an alternating current is made to flow through a disc of metal which is surrounded by copper coil. The disc has a specific diameter and thickness. The secondary current is induced in the disc and it circulates around the outer surface of the disc results heating effect. The switching of power electronic switches is done at various frequencies to get sufficient quick heating response. The fuzzy logic controller uses the error and the rate of change of error as input and the frequency is fed as output to maintain required temperature and in order to minimize losses for modified half bridge resonant inverter fed induction heating system. Here the fuzzy logic controller is designed and simulated with the help of MATLAB to get switching frequency
