| Abstract: | Based on an superior ZVZCT SEPIC topology,the work principle is analyzed,and every element’s parameter of the topology is chosen well when the input voltage is variational and the output voltage is constant. Simulation results show that all the semiconductors can realize ZCT/ZVT in above condition, the loss of the switch is reduced and the converter is the one of the low loss DC-DC converter in a wide range voltage input of the ship’s light substation. |
