摘要：
In order to expand the scope of soft-switching of the dual active bridge series resonant converter (DABSRC), and improve the steady-state performance of DABSRC, the design method of converter according to frequency domain analysis is proposed and the dynamic small signal model of DABSRC is established. Firstly, frequency domain analysis is performed to acquire the operation characteristics of DABSRC. The operation characteristics are utilized to design the voltage gain, quality factor and other parameters of DABSRC. Then, in view of the problem that the converter needs closed-loop control in actual system, the dynamic small signal model of DABSRC is built to provide the basis for the design of closed-loop control. In the end, the Matlab model of DABSRC is set up to prove the effectiveness of analysis method and close-loop control. The results show that the design approach based on frequency domain analysis can ensure the soft switching of DABSRC under different operation conditions, and the steady-state performance of DABSRC can be effectively enhanced by closed-loop control. © 2022 Science Press.
