“…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). Based on verification measurements it was decided to use the simplified TEC model shown in Fig.…”

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.

Based on the principle of electromagnetic induction, this paper proposes a new sleeve structure of electromagnetic induction heating energy storage system, which converts the electrical energy that cannot be consumed by wind power, solar power and other power grids into heat energy. The electromagnetic induction heating model of the eddy current field is established by Ansoft/Maxwell, and the magnetic induction intensity, current penetration depth and current frequency are analyzed. The three-dimensional fluid temperature field and its corresponding temperature characteristics of the system are analyzed by Ansys/Fluent. The temperature field cloud diagram of the sleeve is analyzed. It is concluded that with the increase of air thickness, the loss of the internal iron pipe increases, and the loss of the middle iron pipe decreases. The characteristic curve of the resonant circuit of the electromagnetic induction heating power supply is simulated and analyzed to determine the optimal parameters of the resonant circuit of the induction heating. A 100 kW electromagnetic energy storage system is developed, and the effectiveness and practicability of the method are verified, which can be applied to high power thermal energy storage.

This paper presents the modelling of transduction heaters using the TEC (transformer equivalent circuit) model and FEA (finite element analysis). Each model was used to simulate a set of transduction heating experiments and the results compared. Analysis of the TEC calculated results suggested modification of three parameters: the secondary resistance, the core tube eddy current resistance and the core tube magnetizing reactance. The improved TEC model was then used to design, build and test a 6 kW transduction heater. The measured results are compared with calculated results from the TEC and FEA models. The TEC model accurately predicts the performance of the heater.
