“…The use of wide-bandgap devices in induction heating is currently being researched: Gallium-Nitride (GaN) is proposed in [5] for a modular system running at 2 MHz. Silicon-Carbide (SiC) is employed for a full-bridge resonant converter in [6] and compared to IGBTs and Si-MOSFETs in terms of efficiency in [7]. Different electrical models for the inductive energy transfer path are used in the literature (see [12], [17], [18], [19]): Transformer equivalent circuit (TEC), mutual inductance or a simplified series circuit with only R and L (series equivalent circuit SEC).…”

Induction heating plays an important role in industrial processes and is becoming increasingly important for household appliances such as induction cookers. Most commonly, series or parallel resonant circuits based on IGBT technology are used due to their low cost. In contrast to these, non-resonant converter types are described in this paper for the first time regarding their use in single-phase induction heating applications up to 2 kW. The analysis is based on simulation and measurement results. The proposed non-resonant converter designs offer a very small size and allow full control of the output power. Different pulse pattern for controlling the induction power are investigated. It is found that the full-bridge inverter using block or PSM pulse pattern delivers the best performance and enough power capability. For the test system, the measured average electrical efficiency is 96.8 % over the input power range of 500 W to 1750 W.

“…To ensure the ZVS and ZCS operation of the SRI transistors, it is necessary to provide a certain value of the dead-time between the control signals of the SRI transistors. It should be noted that most authors carry out a mathematical analysis of the SRI output current, taking into account only the first harmonic of the square-wave output voltage of the SRI, and the obtained expressions are used to determine the minimum value of the dead-time [10,13,15,[22][23][24][25]. However, with a low value of the quality factor, using this approach can lead to a significant error in determining the value of the dead-time.…”

Induction heating provides contactless, energy-efficient, accurate, and fast heating of electrically conductive materials. Due to its advantages, IH is increasingly used in different fields such as industry, medicine, and the household sector. High-frequency transistor converters for the induction heating system are often based on series-resonant inverters. This paper analyzes a phase-shift-controlled voltage-source series-resonant inverter for induction heating systems. Mathematical analysis was performed in order to obtain the expressions that describe the output current of the phase-shift-controlled series-resonant inverter in the steady-state mode. Based on the analysis and the obtained expressions of the output current, analytical expressions of the dead-time between the transistors’ control signals of the SRI are obtained. The analytical expressions for determining the value of the dead-time are obtained for two cases: 1) zero value of the phase-shift; 2) the phase shift is greater than zero. To verify the obtained analytical expressions of the output current, validation was performed in the MATLAB/Simulink environment by comparing the peak current values. The verification showed the high accuracy of the obtained expressions, the deviation between the calculated and simulated values of the peak current is less than 0.1 %. The made simplifications of the dead-time expressions also were verified by calculation, the deviation between the calculated values of the drain-to-source voltage at the end of the commutation and the expected value is no more than 3.6 %. The SRI prototype has been designed and implemented in order to validate the analytical and simulation results

Metals must be melted, heated and cooled rapidly or partial heating must be performed in order to obtain weld or alloys from metals in daily life. One of the effective methods used for such needs is induction heating (IH) system. Electromagnetic induction method is the use of heat energy generated by core losses on the heating metal part. These core losses consist of eddy current losses produced by the magnetic fields within the core in the work-piece in the electromagnetic field and hysteresis losses to change the direction of the domains in the iron. In this study, a magnetic model was analyzed for different operating frequencies by 5 turns copper induction coil of metal work-pieces of different material structures with the same dimensions. The magnetic flux density (B) distributions and the skin effect on the work-pieces were examined by using finite element analysis and eddy losses were presented.
