“…In order to drive the work coil at higher frequencies than the inverter (voltage-sourced inverter) is otherwise capable of, some on-the-market models use a circuit that is resonant at an odd harmonic of the switching frequency as proposed in [3][4][5] [6]. Most of these designs operate the coil in the 100kHz-200kHz range at most.…”

Induction heating of aluminum cookware is difficult due to its low resistivity and lack of ferromagnetic properties. Both of these factors result in an effective impedance reflected through the work coil that is too low for practical inverter design and makes efficient coil design difficult. This paper presents a transformer-coupled topology as a means of efficiently delivering the desired amount of power into such low-impedance induction heating loads while keeping the inverter design within practical constraints. This topology consists of a conventional series-load-resonant coil/capacitor circuit. A high-frequency transformer is then used to the couple the series-resonant load to a full-bridge inverter, removing the constraint between load impedance and inverter design. The proposed circuit is built and its operation is experimentally verified.Index Terms--All-metal induction cooker, high-frequency inverter for induction heating, series-load-resonant, transformer impedance matching.

Prevalent converters for induction heating (IH) applications employ two-stage conversion for generating high-frequency magnetic field, namely, AC to DC and then DC to high-frequency AC (HFAC). This research embarks upon a direct conversion of utility AC to high frequency AC with the design of a single-phase matrix converter (SPMC) as a resonant converter using a modified switching technique for IH application. The efficacy of the proposed approach is validated through different attributes such as unity power factor, sinusoidal input current and low total harmonic distortion (THD). The developed prototype-embedded system has high pragmatic deployment potential owing to its cost effectiveness using Arduino mega 2560 and high voltage/current as well as low switching time IXRH40N120 insulated-gate bipolar transistor (IGBT). Different results of the prototype-embedded system for IH application have been verified using Matlab Simulink environment to corroborate its efficacy.

Resonant converters are well suited for induction heating (IH) applications due to their advantages such as efficiency and power density. The control systems of these appliances should provide smooth and wide power control with fewer losses. In this paper, a simple phase locked loop (PLL) based variable duty cycle (VDC) pulse density modulation (PDM) power control scheme for use in class-D inverters for IH loads is proposed. This VDC PDM control method provides a wide power control range. This control scheme also achieves stable and efficient Zero-Voltage-Switching (ZVS) operation over a wide load range. Analysis and modeling of an IH load is done to perform a time domain simulation. The design and output power analysis of a class-D inverter are done for both the conventional pulse width modulation (PWM) and the proposed PLL based VDC PDM methods. The control principles of the proposed method are described in detail. The validity of the proposed control scheme is verified through MATLAB simulations. The PLL loop maintains operation closer to the resonant frequency irrespective of variations in the load parameters. The proposed control scheme provides a linear output power variation to simplify the control logic. A prototype of the class-D inverter system is implemented to validate the simulation results.
