Cascaded full‐bridge resonant inverter configuration for different material vessel induction cooking

Abstract

This paper presents a cascaded full-bridge resonant inverter configuration for different material vessel induction cooking. The proposed inverter configuration features simultaneous heating of three different material vessels, and independent power control. In this proposed work, three different induction heating loads are simultaneously operated at their respective resonant frequencies. Vessels of iron, steel, and aluminium materials are used. The output powers are independently controlled by an asymmetric duty cycle control. The proposed inverter is designed and hardware prototype has been implemented. Experimental results are validated with simulation results.

Development of a Coaxial Dual-Coil Induction Heating System With a Composite Bridge-Type Inverter and a Flexible Switching Mechanism

“…However, impedances are different for the inner and outer coil, it also poses a very serious challenge due to the need to provide power supplies of different levels for the inner and outer coil. Reducing the number of inverters needed is one of the key points of discussion; some literature also improves the structure of inverters [25][26][27] to reduce the number of inverters and the overall circuit size, Additionally, some literature discusses the use of power components and the number of heating loads, paired with independent power control, utilizing different operating frequencies [28][29][30][31], to achieve efficient electric power transmission. However, the control strategy for this type of circuit is quite complicated, and more rigorous consideration is required in the design process to avoid control errors that cause a heating system failure.…”
