摘要

Induction heating (IH) is the most common type of heating used in the modern era owing to its fast response, higher efficiency, cleanliness, safety, and precise control. Among all the potential applications of IH, induction cooking (IC) has gained popularity due to escalating gas fuel prices and lower carbon footprint. The demand for multi-load IC systems is increasing day by day. In a multi-load IC system, each load can be fed by an individual inverter which will have independent control but will increase the system cost, mass, and volume of the system. Consequently, to maintain the ability to control each load independently, minimizing the number of components and the volume of the converter is imperative. This paper proposes a three-load IC system with a full-bridge (FB) inverter. The control technique employed is cyclic ON–OFF control which enables the loads to be controlled concurrently and independently. A prototype of 1.05 KW is simulated using MATLAB-SIMULINK and validated by experimentation. The simulation and experimental results are in good agreement. The maximum efficiency obtained is 98.08%. A thorough analysis of losses is also carried out for clear comprehension. The proposed inverter is a simple and inexpensive solution for multi-load IC applications.
