One of the main problems of power inverters designed for induction heating home appliances is the broad variance of possible loads. One-switch resonant inverters for induction heating are designed to increased power as frequency decreases; duty cycle is later computed to achieve Zero Voltage Switching (ZVS) condition. To further reduce the output power, over minimum at obtained at Zero Voltage and Derivate Switching (ZVDS), and allow independent control of power with frequency, sophisticated control techniques need to be applied, but depending on load, non-ZVS switching conditions may occur therefore degrading the performance and efficiency. This paper proposes a regenerative inductive snubber capable of reduce transistor losses in non-ZVS conditions. In this proposal, the snubber is actually a minor part of the induction coil. Therefore, the power delivered to the snubber is part of the output. Experimental results show good agreement with the theoretical equations.

“…However, the capacitor value might be changeable to create multiple resonant frequencies using additional circuits [13]. For the VSI reported in [2], [14], the capacitor is connected in series with the load inductor to create resonance. The voltage gain of this inverter is a function of the switching frequency and has a maximum of 1 [3].…”

Some of the problems with photovoltaic projects for household applications are the cost, efficiency and complexity of the inverter. various inverter topologies are in use but they do not provide a boost and true sinewave voltage without additional complex circuitry. A double-switch resonant inverter with two different capacitor configurations is proposed in this paper. The performance of this topology is verified both by simulation and experimentally. The output voltage of the proposed resonant inverter has a true sinusoidal waveform at no-load, pure capacitive and pure inductive load conditions. At resistive load, the waveform is noticeably near sinusoidal and the THD is nonzero. Formulae for the resonant frequency and the voltage gain are derived and verified. The circuit was tested under different operating conditions and parameters for achieving zero-voltage switching (ZVS). The results show that there are no stability issues with the proposed circuit and that a closed-loop control is not required. The proposed topology is applicable to a wide range of loads and dc voltage sources at power-line frequencies.

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.
