“…Series resonant inverter consists of an LC resonant tank and switching elements which are connected in series with the load to form an under damped circuit [13]- [15].Oscillating voltage and current, due to LC resonance tank are applied to the load and the inverter switches can be switched at zero voltage or zero current. Fig.2 shows the full bridge SRI.…”

Resonant inverters are widely used in induction heating applications. Series Resonant Inverter (SRI) fed with voltage source is very much reliable, cost-effective and provides various power control techniques. Different power control schemes like phase shift control (PSC), asymmetrical duty cycle (ADC) control, asymmetrical voltage cancellation (AVC) control, pulse density modulation (PDM) control are normally used at SRI for high frequency induction heating. In this paper a new hybrid control technique by combining PSC and PDM is analyzed. The new control technique overcomes the drawback of individual scheme and provides a wide range of power control. The analyses of all the control techniques are verified through MATLAB simulation results

A topology named L-LC resonant inverter (RI) for induction heating (IH) applications takes most of the merits of the conventional series and parallel resonant schemes, while eliminating their limitations. In this paper, fundamental frequency AC analysis of L-LC RI is revisited, and a new operating point is suggested featuring enhanced current gain and near in-phase operation as compared to the conventional operating point. An approximate analysis of the circuit with square-wave voltage source is also described highlighting the effect of auxiliary inductor on the source current waveform. The analysis also leads to an optimum choice of the auxiliary inductance. The requirements of the metal organic vapour phase epitaxy (MOVPE) system in which a graphite susceptor is required to be heated to 1200 ∘ C demanding a 25 kW, 25 kHz IH power supply, the configuration of developed IH system, and experimental results are presented.

“…Besides, the equipment volume is decreased and ozone production can easily be controlled. Among the different converters used in power electronics, resonant converters are widely employed in applications such as dc-to-dc conversion, lamp ballast, electronic welders, electrostatic applications and induction heating [3][4][5][6][7][8][9]. These converters employ a resonant circuit to obtain sinusoidal voltage and current waveforms in the power switches, therefore providing soft-switching and reducing losses and EMI/RFI.…”

The use of supply frequencies above 50-60 Hz allow to increase the power density applied to the ozonizer electrode surface and increase ozone production for a given surface area, while decreasing the necessary peak voltage. Parallel resonant converters are well suited for supplying the high capacitive load of ozonizers. Therefore, in this paper the current-fed parallel-resonant push-pull inverter is proposed as a good option to implement high-voltage high-frequency power supplies for ozone generators. The proposed converter is analyzed and some important characteristics are obtained. The design and implementation of the complete power supply are also shown. The UC3872 integrated circuit is proposed in order to operate the converter at resonance, allowing to maintain a good response disregarding the changes in electric parameters of transformer-ozonizer pair. Experimental results for a 50W prototype are also provided.
