    This paper presents the design and concept of fuzzy phase-lock loop for a two-output high-frequency series-resonant induction heater. This conceptual controller is applied for an unknown mathematical model as well as this prototype, which is used to maintain Zero-Voltage Switching condition along with the period by automated adjusting switching frequency. The power of the prototype can be controlled by using 3 branches of full bridge series-resonant inverter: one branch for common controlled and others controlled for each independently two-output. The simulation result is verified by MATLAB/Simulink®.

    This paper presents the design and concept of fuzzy logic controller analysis of two-output high-frequency series-resonant induction heater. The fuzzy logic controller is applied for non-linear load and unknown mathematical model as well as this prototype, which is used to control the duty-cycle of power switch to maintain current output. The power of the prototype can be controlled by using 3 branches of full bridge series resonant inverter: one branch for common controlled and others controlled for each independently two output. The power for others can be controlled by the asymmetrical voltage cancellation methodology. © 2014 IEEE.
