Design, Modelling, Simulation and Comparison of Class E & Class F3 Amplifier Systems

The main objective of this paper is to design and compare the class-E and class-F3 amplifier systems for induction heating application. The power frequency alternating current is transformed into direct current using diode rectifier with c-filter. The voltage across the capacitor filter is applied to class E/class F3 amplifier system. The circuit parameters of class E and class F3 are designed and simulation studies are performed. The results of the above mentioned systems are compared in terms of output power and THD. The simulation results signify the performance of class-F3 amplifier system is superior to class-E amplifier system and class-F3 amplifier has advantages like single power switch and higher output power.
