Induction heating is extensively utilized in various applications such as melting, metal forming, and heat treating. To facilitate high-frequency (HF) induction heating, a power electronic inverter has been specifically designed. This paper focuses on the development of a series resonant circuit for metal forming purposes. The series resonant circuit is designed with three different switching frequency cases. The paper also presents simulations of the HF inverter design, modeling, and control circuits. In recent times, there has been a growing interest in domestic-level induction heating processes due to their clean, reliable, flexible, and fast operation. To regulate the output power, a simplified pulse width modulation (PWM) switching control method was employed. The maximum output power is achieved when the switching frequency matches the resonance frequency, as there are no switching losses compared to frequencies higher or lower than the resonance frequency. In this case, the power and efficiency achieved are 1014W and 92.4%, respectively. Therefore, it is crucial for the switching frequency to align with the resonance frequency in order to obtain optimal results. This study effectively demonstrates the proposed system's effectiveness for metal treatment induction heating systems.
