-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 equivalent parameters are valid only for a given intensity of the magnetic field. In the simple case of a cylindrical workpiece in a long inductor, the equivalent impedance has the form (3) (Sluhotkii & Rîskin, 1982 In case of strong coupling and large variation of the operating frequency, a "large bandwidth" model can be used (Forest et al, 2000) in order to take into account the frequency-dependence of the equivalent parameters (Fig. 5).…”

“…The coil and vessel are similar to the primary and secondary of a transformer. Based on this, induction cooking load in referrence to the coil is modeled as a series R eq -L r circuit for constant switching frequency operation [12], [20]- [24]. R eq is the referred equivalent resistance and L r is the referred equivalent inductance to the coil, respectively.…”

“…The main function of inverters in multiple-load induction cooking systems is to reduce components count, simultaneous and independent control of each load, and high conversion efficiency. An inverter with two loads is proposed and analyzed in [12]. This method has one master and one slave load, and uses several resonant capacitors connected in parallel with electro-mechanical switches.…”

Inverter configurations for multiple-load induction cooking applications need development. Inverter configurations for induction cooking applications are used in home appliances based on single coil inverters. For multiple-load configurations, multiple coils are used. They require proper inverters, which provide independent control for each load and have fewer components. This paper presents a three-leg inverter configuration for three load induction cooking applications. Each induction coil powers one induction cooking load. This configuration operates with constant switching frequency and powers individual loads. The output power of the required load is controlled with a phase-shift control technique. This configuration is simulated and experimentally tested with three induction loads. The simulation and experimental results are in good agreement. This configuration can be extended to more loads.
