Abstract

Background and Objectives: This paper presents a high-performance and efficient circuit based on low-cost coils for induction heating applications. We design the coils specifically for induction sealing and induction cooker applications. The proposed circuit utilizes two parallel sets of MOSFET transistors to increase the current flow and output power.
Methods: Three types of coils have been developed in square and rectangular designs on the printed circuit board (PCB). In this case, the construction process is simple and requires minimal time. Induction coils designed for induction sealing applications have a rectangular structure that effectively seals a wide range of bottles.
Results: The flexibility of the proposed circuit is one of its advantages; the output frequency can be adjusted by increasing or decreasing the number of capacitors in the capacitor bank. Performance comparisons (e.g., efficiency, power density, cost) between the proposed method and other studies show that the implementation cost of the proposed circuit is lower than that of others. The proposed circuit achieves 95% efficiency. Thermal imaging confirms the circuit's performance. Based on the electromagnetic interference results, the circuit's performance is not affected by an external magnetic field.
Conclusion: The proposed circuit has been tested with different capacitor banks using two power supplies of 24 V and 12 V. The peak-to-peak output voltage is 181 V and 92 V for the 24 V and 12 V power supplies, respectively. The results demonstrate that the circuit and coils are suitable for induction heating applications.
