Abstract
The dynamic characteristic and working efficiency are key performance indexes of a bidirectional DC-DC con?verter. In this paper,the topological principle and working process of a CLLLC resonant bidirectional full-bridge DC-DC converter were analyzed in detail,and the resonant parameters of the primaryand secondary sides of this converter were designed;meanwhile,the closed loop control strategy based on input voltage feed-forward and output voltage feed?back was proposed,under which the pulse frequency modulation method was used to generate the driving waveform. Fi?nally,theconverter was modelled and simulatedin Matlab environment. Results show that the resonant and soft-switch?ing characteristics of the CLLLC resonant bidirectional full-bridge DC-DC converter were realized,and it had better dy?namic performance and higher working efficiency,thus verifying the feasibility of the proposed control strategy and the correctness of parameter design.关键词
