| Abstract: | In this paper,the work characteristic and parameter designing of SEPIC topology as well as its soft switching are studied in details.The soft switching realization qualification of wide-range input voltage is obtained by analysis.Furthermore,the parameters are optimized by using MATLAB simulation.In the experiments,relevant parameters and the efficiency of system are measured or calculated with wide-range input voltage,the zero-voltage zero-current turn-on and turn-off of the main and assistant switching tubes can well realized with its loss reduced and efficiency enhanced.The converter is the one of the high efficiency DC-DC converter in a wide range voltage input of the ship. |
