High-Efficiency SiC Half-Bridge Coupled Package for 3.5kW-class Induction Heating Systems

Inhalt:
A novel half-bridge coupled power module integrating two Silicon Carbide (SiC) MOSFET devices for commercial induction heating systems up to 3.5 kW is introduced in this paper. Key features of the new module, including its internal packaging structure and enhanced high-frequency switching performance, are analyzed in detail. Laboratory experiments on a 3.5 kW induction heating system validate the module’s performance under practical operating conditions, showing significant improvements in power density, thermal management, and overall system efficiency. These results indicate the potential for more compact and efficient induction heating solutions in the commercial food service industry, with improved energy savings, cooking performance, and equipment durability.
