摘要
In this paper, an improved bidirectional resonant converter for wide battery voltage applications is proposed. The topology has a symmetrical resonant circuit which guarantees an identical behaviour for both energy transfer directions. The proposed converter has the capability to achieve soft switching for both bridges and the ability to operate under wide input/output voltage with narrow switching frequency variation. That increases the efficiency for both energy transfer directions. First harmonic approximation method (FHA) is used to define the equivalent circuit and to analyse the gain characteristics of the converter. Performances of the proposed converter for wide battery voltage application are evaluated through some simulations using Matlab/Simulink software.
