To solve the problem of simultaneous transmission of radio energy and information,a double-full-bridge structure is proposed to realize two-way and reverse transmission of electric energy and information.Firstly,the mathematical model is established to derive the relationship between the direction of power transmission and the phase shift angle.Secondly,in order to achieve reverse information transmission while transmitting electric energy,a new magnetic interface is added to the main structure of electric energy transmission for information transmission.Finally,the feasibility of the structure is verified by simulation,and the bidirectional transmission of electric energy and the reverse transmission of information are realized.
