-Induction cooking application with multiple loads need high power inverters and appropriate control techniques. This paper proposes an inverter configuration with buck-boost converter for multiple load induction cooking application with independent control of each load. It uses one half-bridge for each load. For a given dc supply of V DC , one more V DC is derived using buckboost converter giving 2V DC as the input to each half-bridge inverter. Series resonant loads are connected between the centre point of 2 V DC and each half-bridge. The output voltage across each load is like that of a full-bridge inverter. In the proposed configuration, half of the output power is supplied to each load directly from the source and remaining half of the output power is supplied to each load through buck-boost converter. With buck-boost converter, each half-bridge inverter output power is increased to a full-bridge inverter output power level. Each half-bridge is operated with constant and same switching frequency with asymmetrical duty cycle (ADC) control technique. By ADC, output power of each load is independently controlled. This configuration also offers reduced component count. The proposed inverter configuration is simulated and experimentally verified with two loads. Simulation and experimental results are in good agreement. This configuration can be extended to multiple loads.

“…This can be contrasted with other heating methods where heat is generated in a heating element or flame, which is then applied to the work-piece. Hence in the cooking market, domestic induction heating is becoming a standard option due to its benefits such as higher efficiency, cleanness and the reduced heating times In order to implement this type of appliances, a converter of wide bandwidth (typically 20 to 100 kHz) and high power output ( up to 5 kW [1]- [2]) is required. The development of high frequency AC/AC converters for kitchen equipments is need of the hour [1].…”

Domestic induction heating (IH) is currently the choice in modern domestic application due to its advantages regarding fast heating time, efficiency and improved control. Induction heating applications require high frequency currents which are obtained using resonant converters. In this paper a novel DC-AC single phase inverter is proposed and simulated using MATLAB. When the switches are turned on and off, a conventional inverter generates switching loss because of the hard-switching. Thus the inverter loss is increased. Proposed system contains auxiliary circuit. The converter stage switches perform soft-switching because of the auxiliary circuit. Therefore all switches perform softswitching when the switches are turned on and off. Thus the proposed system reduces switching loss and voltage stress.

“…Different power control and regulation strategies have been proposed such as pulse width modulation (PWM), pulse frequency modulation and phase shift control. These power control schemes may cause high magnitude of switching losses, because it is not always possible to turn on or off the switching devices at zero voltage or zero current instants (Lucia, Burdio, Millan, Acero, & Puyal, 2009;Pham, Fujita, Ozaki, & Uchida, 2011). Power control by variable frequency operation (Sarnago, Lucia, Mediano & Burdio, 2013a) has several disadvantages including high electromagnetic interference, poor utilization of the components and complex filtering of output voltage ripple.…”

ABSTRACT. This paper discusses about the fixed frequency pulse mask control based high frequency AC conversion circuit for industrial induction heating applications. Conventionally, for induction heating load, the output power control is achieved using the pulse with modulation based converters. The conventional converters do not guarantee the zero voltage switching condition required for the minimization of the switching losses. In this paper, pulse mask control scheme for the power control of induction heating load is proposed. This power control strategy allows the inverter to operate closer to the resonant frequency, to obtain zero voltage switching condition. The proposed high frequency AC power conversion circuit has lesser total harmonic distortion in the supply side. Modeling of the IH load, design of conversion circuit and principle of the control scheme and its implementation using low cost PIC controller are briefly discussed. Simulation results obtained using the Matlab environment are presented to illustrate the effectiveness of the pulse mask scheme. The obtained results indicate the reduction in losses, improvement in the output power and lesser harmonic distortion in the supply side by the proposed converter. The hardware results are in good agreement with the simulation results.
