Abstract: This paper proposes a cost-effective series resonant inverter employed in applications of induction heating. The proposed inverter operates with high-frequency pulse-density modulation strategy for soft-switching. The high-frequency operation (20 kHz – 100 kHz) of this inverter results in a nearly sinusoidal output that is suitable for relatively fixed output applications such as induction heating. The series resonance circuit comprises an inductor and a capacitor that are in series with the load. The small size of resonating components is due to the high-frequency switching operation. The practical effectiveness of induction heating power supply is substantially proved by implementing a prototype series resonant inverter. To analyze the performance, comparison between the simulation and experimental results is done by using PSIM program
