This paper presents an analysis of a dual output domestic induction cooker incorporating two half-bridge resonant inverters.
The two inverters are subjected to asymmetrical duty cycle phase-shift control strategy to smoothly vary their output powers.
This control technique ensures better and more effective performance compared to other conventional control techniques. Both
the inverters are connected to two partly magnetically coupled inductive loads sharing a common resonant capacitor. Both the
inverters operate with the same switching frequency avoiding inter modulation acoustic noises due to the magnetic coupling
between the two loads. The entire system is analyzed and the simulation is accomplished with the help of power system simulator
(PSIM) software. The results obtained from the simulation are finally verified with the results obtained from the real time
