-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.

“…The main reason for this is generally understood that the output capacitor C oss in the switching power MOSFET (2) (3) must be controlled to entirely discharge itself before the next coming turn-on (2) , but the detailed analysis to explain the internal operating mechanism of the circuit both theoretically and experimentally is still kept unreported. This is a very interesting problem and is taken as our research topic in this paper.…”

“…In the single-phase full-bridge inverter circuit using MOS-FET power switching device with a load of induction heating, one important problem encountered in the circuit is when the inverter is operated with phase-shift control since the switching frequency f s must be always slightly increased with the increase of phase-shift in order to maintain the inverter to operate under Zero Voltage Switching, ZVS condition (1) (2) which is regarded as an important necessary operating condition. The main reason for this is generally understood that the output capacitor C oss in the switching power MOSFET (2) (3) must be controlled to entirely discharge itself before the next coming turn-on (2) , but the detailed analysis to explain the internal operating mechanism of the circuit both theoretically and experimentally is still kept unreported.…”

MemberThis paper presents a detailed analysis of circuit operation under ZVS and NON-ZVS conditions in a full-bridge high-frequency phase-shift control series resonant MOSFET inverter with the load of induction heating. Various modes of circuit operation both under ZVS and NON-ZVS conditions are first analyzed in details. The voltage and current equations of these circuits are then obtained and used for calculation of the waveforms by MATLAB program. The calculated results can lead to the consideration of various circuit parameters that determine ZVS or NON-ZVS operating conditions. The theoretical results are also verified by experimental ones, using a prototype test set rated at 3 kW.

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.
