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

The bidirectional Wireless Power Transfer(WPT) apparatus for the vehicle to home(V2H) is discussed in this study. It utilizes a straightforward, small single-ended converter and a cooperatively synchronized phase-difference control mechanism. This paper illustrates the configuration of the wireless V2H system as well as the operation of the bidirectional wireless power transmission. Practical solutions to issues with operational frequency stability are explored. It is shown that the phase difference between the power supplying and the power receiving circuits determines how much power is transferred.A dual-active phase-shift power-variable constant-frequency single-ended bidirectional converter control approach with mutually synchronized phase-difference is proposed. It is simple to validate that the designated frequency band complies with international requirements because the wireless V2H system can be operated under a consistent operating frequency [1]. Despite the low coupling coefficient between the transfer coils, the high-power wireless transmission is accomplished via the optimal phase difference. In addition, compared to the prior frequency-controlled system, the suggested system ensures the stability of the power transfer operation against parameter change. The newly created single-ended, low-cost wireless V2H system is thus ready for mass manufacturing.
