Full-bridge series resonant multi-inverter featuring new 900-V SiC devices for improved induction heating appliances

Induction heating is a key technology due to its advantages in terms of performance and efficiency. Recent developments in domestic induction heating including flexible cooking surfaces with multiple output power converters. Besides, advances in wide bandgap devices allow new design possibilities such as cost-effective and high efficiency power converters. In this paper, an improved full-bridge series resonant multi-inverter with SiC devices is presented. The proposed converter and the modulation strategies to obtain proper output power control are detailed. Finally, a two-load experimental prototype is built, showing the experimental results and the advantages of the converter.
