چكيده فارسي :
In this paper, a new high step-up converter without a coupled-inductor at the input is presented. The converter has two duties of coupled inductors, one is applied to increase the voltage gain and the other is applied to create zero current switching conditions and snubber energy transmission. A lossless snubber has been applied to provide soft switching conditions. All diodes are turned off at zero current switching, so they do not have a reverse recovery problem. The converter has been completely analyzed and a 60-W of it has been simulated in PSPICE to confirm the circuit analysis.
