Research on Modeling and Control Strategy of Bidirectional Wireless Power Transfer System
摘要
In order to improve the transmission distance of the LCC-LCC type bidirectional wireless power transmission system, this paper designs a BWPT system with a transmission distance of 35 cm. By modeling and analyzing the efficiency of the LCC-LCC type compensation topology, the relationship between the system's external phase shift angle and the output power and transmission efficiency is analyzed. On this basis, a BWPT system power control strategy is proposed to achieve control of the power flow. Finally, a preliminary experimental verification of the designed BWPT system is carried out by building an experimental platform to prove the feasibility of the proposed system.
