| Abstract: | An active clamped topology for ZVS-SEPIC is proposed.The resonant effect on the converter is reduced in the converter because of using auxiliary switch and pulse width modulation.And the efficiency of converter is increased because main and auxiliary switch can be turned on ZVS.The principle and design of LC resonant network is analyzed.The experimental results verify the validity of the theory. |
