Modern induction cookers have started to demand challenging features such as slim design, high power ratings, high performance, and silence. All those requirements are directly related to the power semiconductors used in power converters. Si (silicon)-based power semiconductors are not capable of answering those demands because of strict operating conditions, such as high ambient temperatures. Therefore, WBG (Wide Band Gap) power semiconductors have been getting attention. In this study, WBG power semiconductors will be compared with Si-based IGBT (Insulated Gate Bipolar Transistor) under different operating conditions. The best option to use WBG power semiconductors in modern induction cookers will be analyzed. The performance of a series-resonant half-bridge converter was evaluated under various operating conditions. Measurements were obtained from the real operating conditions of induction hobs. The switching frequency is changed from 20 kHz to 100 kHz, while the power rating is increased to 3.7 kW. In addition to traditional 4-zone induction cooktops, this discussion also provides a comprehensive analysis of high-segment, fully flexible induction cooktops. While the IGBT-based design exhibits 25.79 W power loss per device, the WBG device exhibits 6.87 W in the maximum power condition of conventional induction cooker operation. When it comes to high-frequency operation, the WBG power device exhibits 10.05 W at 95 kHz. Total power loss is still well below that of the IGBT-based conventional design. Appropriate usage of WBG power semiconductors in modern induction cookers can exploit many more benefits than Si-based designs.

“…Based on the power conversion stages, the IH converter topologies are classified into two types, namely dual-stage power conversion (AC-DC-AC) and single-stage power conversion (AC-AC). The most commonly used two-stage topologies are single-switch (SS) resonant inverters [13][14][15][16] half-bridge (HB) inverter [17][18][19][20][21] and full-bridge (FB) inverter. [22][23][24][25][26] These topologies are used to feed power, either to single or multi-loads, with additional modifications.…”

The concept of induction heating is slowly entrenching as it has the traits of homogeneous heating, zero pollution and higher power density. To achieve these traits convincingly in reality, there is a need to develop energy efficient converter topologies, which aid in achieving power regulation of soft switching and very high frequency operation. This paper presents the salient features of converter topologies used for domestic and industrial heating applications with a focus on its stage-wise power conversion, power density, load handling capacity, soft switching, reliability and size. The performance of these topologies is analysed in terms of converter switching frequency, power rating, modulation techniques, flicker, user performance and efficiency. Moreover, this review paper predicts the future trends associated with the adaptation of wide band-gap power semiconductor materials, multi-output topologies, variable frequency control scheme with minimum losses and filter design to improve source-side power factor. The detailed technology review will be extremely useful for researchers, designers and engineers in choosing the appropriate topology for the chosen application.

“…There are several reports on evaluation of HF IH converters using SiC power devices, particularly, HF inverters [7][8][9][10][11]; however, we are not aware of any study cases or academic papers verifying soft-switching techniques, especially ZVS, using all-SiC power modules with regard to SiC-MOSFET characteristics. In this context, it is important to experimentally verify all-SiC power modules, combining high withstand voltage, low on-resistance, and zero tail current, as an alternative to Si-IGBT power devices (modules or discrete components), being currently the mainstream in home and professional high-frequency (HF) IH applications.…”

This paper presents a novel prototype of a singlestage zero voltage soft-switching pulse-width modulation -controlled ac-ac converter with a silicon carbide (SiC)-MOSFET/SiC-SBD power module for high-frequency (HF) induction heating (IH) applications. The newly developed ac-ac converter can achieve higher efficiency than a Si-IGBT/Si-PN diode power module-based prototype due to a low ON-resistance of SiC-MOSFET and a low forward voltage of SiC-SBD under the condition of HF switching. The performances of the new prototype converter are evaluated by experiment with a single-phase IH utensil of ferromagnetic stainless metal, after which the high-efficiency and low switching noise characteristics due to the all SiC power module are actually demonstrated.
