A Dual-Active Single-Ended Wireless V2H System with Self-Synchronized Phase-Difference Control Method

This paper discusses the bidirectional Wireless Power Transfer (WPT) device for vehicle-to-house (V2H). It uses a simple, compact single-ended converter and self-synchronized phase-difference control mechanism. This paper proposes a way whereby phase difference control could be self-contained on the slave side without mutual communication. This method allows for high-power wireless transmission despite the low coupling coefficient between the transfer coils. The phase difference and transmission power can be altered by changing the MOSFET conduction time on one side without synchronizing the phases on both sides.
