At the heart of induction heating systems lies the inverter, a crucial component that converts electrical energy into the high-frequency alternating current (AC) necessary for efficient induction heating. The performance of the inverter is critical, as it directly affects the overall efficiency, cost, and reliability of the system. In recent years, there has been a growing focus in power electronics on maximizing efficiency by minimizing the number of components in these systems[2]. This approach not only leads to more compact designs but also enhances performance and reduces manufacturing costs. However, this pursuit of efficiency presents its own set of challenges.
advanced in recent years, driven by their numerous benefits, including efficient, clean, and safe contactless energy transfer. This technology has already made a significant impact on the market, both in terms of adoption and economic effect. Central to these systems are inverters, which, when utilized effectively, can lower overall costs and improve system efficiency. The current focus in power electronic converters is on maximizing efficiency by reducing the number of components, leading to more compact, cost-effective designs with higher performance. However, power electronic switches introduce challenges such as electromagnetic interference (EMI), switching losses, and stress, which can increase costs, reduce efficiency, and necessitate additional maintenance. As a result, engineers are increasingly concentrating on developing converters with minimal components to address these issues.
Power electronic converters, particularly those involving high-frequency switching, introduce several undesirable factors that can adversely affect system performance. These factors include electromagnetic interference (EMI), switching losses, and thermal stress, all of which contribute to higher operational costs and lower efficiency. For example, EMI can disrupt the operation of nearby electronic devices, necessitating additional filtering and protective measures. Switching losses occur when power is dissipated during the transition between the on and off states of the electronic switches, which reduces the overall efficiency of the system. Thermal stress, caused by the rapid switching and high power levels, can lead to component degradation over time, increasing maintenance needs and the likelihood of system failure.
This paper introduces a multiple-output boosted resonant inverter aimed at improving the efficiency and performance of modern induction heating systems. The proposed design is capable of powering multiple induction loads while reducing current levels, thereby significantly enhancing converter efficiency. This approach enables a highperformance, cost-effective solution. A prototype has been constructed and tested to confirm the viability of the proposed converter, with simulations conducted using MATLAB/Simulink to support the findings.
To address these challenges, modern engineers are increasingly focused on designing power electronic converters that use the fewest possible components while maintaining high efficiency and performance. The goal is to create systems that are not only cost-effective but also reliable and easy to maintain. This trend has led to the exploration of various inverter topologies and control strategies aimed at optimizing the performance of induction heating systems[3].

1.INTRODUCTION Induction heating technology has rapidly gained prominence due to its many advantages, such as high efficiency, cleanliness, and safety. These benefits have driven significant advancements in the field, leading to widespread adoption and notable economic impact. Unlike traditional heating methods that rely on direct contact or convection, induction heating works through electromagnetic induction to generate heat directly within the material. This method of contactless energy transfer offers unmatched precision and control, making it an ideal choice for a variety of applications, ranging from industrial processes to household appliances like induction cooktops[1].
