Abstract

This paper proposes a method for controlling energy distribution to 1 phase induction heating coil by using the binary rate modulation (BRM) Technique. Such method provides proper frequency to the heating coil´s requirement by control the frequency at the resonance point, that is, 64-kHz frequency band. System design are classified to 2 parts. The first part determines main frequency, and the second part generates the frequency from the 8-bit BRM derived from IC no. PAL22V10 in order to control the frequency for full-bridge connected inverter when supplying the energy required by the 1 phase induction heating coil. Therefore efficiency of the energy supply can be increased.
