In the current scenario, power electronic device-based induction heating (IH) technologies are widely employed in domestic cooking, industrial melting and medical applications. These IH applications are designed using different converter topologies, modulation and control techniques. This review article mainly focuses on the modelling of half-bridge series resonant inverter, electrical and thermal model of IH load. This review also analyses the performance of the converter topologies based on the power conversion stages, switching frequency, power rating, power density, control range, modulation techniques, load handling capacity and efficiency. Moreover, this paper provides insight into the future of IH application, with respect to the adaptation of wide band-gap power semiconductor materials, multi-output topologies, variable-frequency control schemes with minimum losses and filters designed to improve source-side power factor. With the identified research gap in the literature, an attempt has also been made to develop a new hybrid modulation technique, to achieve a wide range of power control with high efficiency. A 100 W full-bridge inverter prototype is realised both in simulation and hardware, with various modulation schemes using a PIC16F877A microcontroller. The results are compared with existing techniques and the comparisons reveal that the proposed scheme is highly viable and effective for the rendered applications.

“…In particular, the electrical efficiency of the inverter -which, in literature, is given by authors as a criterion for the assessment of the made structures -slightly more than 90% at the operating frequency of 565 kHz for the load diameter of Ø4 mm. The authors [1] indicate the efficiency of their unit as being near 83% (they do not precise a method of measurement) at the frequency of 20 to 50 kHz, which corresponds to the operating frequency: 11 ÷ 28 times lower than the control frequency of the inverter analyzed in this paper.…”

The paper is an attempt of discussion and presentation of the concept of a method for determining efficiency of high frequency inverter systems used in electroheat processes. Based on the example of a constructed model of a single -switch Class E ZVS-1S quasi-resonant inverter and the obtained results of its measurements, an effort of assessment of the inverter performance and its efficiency has been made. The paper presents a brief analysis of the operation and basic relationships in the inverter, the concept of control, conceptual design, difficulties during its implementation and it also identifies sources of power losses in the inverter and determines its efficiency for various load parameters.Streszczenie. Artykuł jest próbą dyskusji i przedstawieniem koncepcji metody wyznaczania sprawności układów falowników wysokoczęstotliwosciowych wykorzystywanych w grzejnictwie elektrycznym. Na przykładzie wykonanego modelu układu jednołącznikowego falownika napięciowego ZVS-1S klasy E i wyników zrealizowanych pomiarów podjęto próbę oszacowania jego sprawności.

“…Many investigations made great contributions to the study of spiral coils, magnetic induction, and circuit topologies for performance improvement, and established a research foundation for subsequent studies. Benefiting from the contribution of the single-ended resonant induction cooker proposed in the literature [4], extensive research has been carried out on household induction cookers. The half-bridge series-resonant inductionheating (HB SR-IH) cooker was subsequently developed for further increased efficiency and output power, in which contributions to load commutation and forced commutation power control were presented [5,6].…”

This paper presents an analysis and design strategy for a half‐bridge series resonant induction heating (HB SR‐IH) cooker powered by a rectified sinusoidal DC. The simplified equivalent circuit of an induction cooker is modelled by a train of rectified sinusoidal DC pulses chopped at the switching frequency. An average root‐mean‐square (RMS) method is proposed to calculate the RMS resonant voltage and current extrapolated to the power line frequency period. The stability of the cooker is achieved by properly setting the damping ratio in the root‐locus plane to keep the system running quasi‐resonantly at the required power. The power control of the SR HB‐IH cooktop is performed by forced commutation above the resonance frequency. A prototype of a 3 kW HB SR‐IH cooker was designed and implemented to validate the estimated results. Various waveforms from low power to high power are discussed and verified by damping ratio control. The SR HB‐IH cooktop achieves a high‐power factor of 0.95 to 0.995 when generating 300W to 3kW due to less filtered DC power. The power quality assessment showed that the total harmonic distortion (THD) of the line current and voltage measured at 3 kW was 4.1% and 3.5%, respectively.
