High-Power/High-Temperature Fluid Water Induction Heating System based on a SiC-MOSFET Single-Ended High-Frequency Resonant Inverter

In this study, a single-phase induction heating (IH)-applied water heating system with Silicon Carbide (SiC) MOSFET-based single-ended high frequency inverter is presented for home and consumer appliances. The proposed system exhibits high thermal response for fluid heating due to the ferromagnetic/non-ferromagnetic materials and work-coil structure. They which are suitably designed for electric heating as well as the newly-developed high-frequency inverter. Thus, efficient electric-thermal energy conversion is expected. This is competitive for conventional gas-based fluid heating. The performances of the proposed fluid IH system are demonstrated with a 5-kW prototype together with the relevant analysis and design. Subsequently, the feasibility is evaluated based on practical applications.
