In this paper, resonant inverters for induction heating are developed for domestic applications. the design is based on half and full bridge single phase inverter of 1 and 4 kW rating. First, the power circuits of the two topologies are analyzed using computer aided design based on Simplorer package. then, an experimental system was built and tested using microcontroller chip (PiccoloTMS320F28027). the performances of the. topologies are highlighted and assessed. the obtained results show that two systems are able to operate satisfactory under soft switching at high frequency with high efficiency. the power control is more interesting for full bridge particularly when the angle phase control is considered. Further, the experimental results agree well withthose obtained withthe CAD design. this validates the design model used for the purpose. the experimental system shows high integration and flexibility to incorporate other control strategies whereby higher efficiency can be achieved.
