Abstract :
This paper proposes an online load estimation algorithm of LCL-resonant type induction heater and effective temperature control method to increase uniformity and efficiency. Adaptive parameter estimation method was used to find out an equivalent resistance and inductance of a work piece with only two voltage sensing(inverter voltage and capacitor voltage) and additional ferrite core was arranged for effective heating. Simulation and experimental results are presented to verify proposed methods.
