Fuzzy Logic Control of A Two-Output High-Frequency Series-Resonant Induction Heater

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 dutycycle 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.
