Comparative study of IGBT and SiC-MOSFET in a wireless V2H system with a new bidirectional single-ended ZVS converter

The smart house system offer promise as an effective solution to environmental problems. An obstacle to diffusion of the smart house is the high cost of battery. An effective solution to this problem is vehicle to home (V2H) system. EVs can be used in smart house systems to supplement the energy storage. This system essentially requires a bidirectional power transfer feature between the EV and home. The wireless power transfer (WPT) system is very suitable for smart house, because it's can eliminate the use of power cables with plug. Proposed is a new bidirectional wireless power transfer system for V2H with simplest components and low cost aiming at wide diffusion in this paper. Described is a comparative loss evaluation of power devices which include a newly developed SiC-MOSFET utilized for a novel type of bidirectional wireless EV charging system with an efficient and compact type single-ended quasi-resonant high-frequency inverter for V2H.
