In this paper, a new non-isolated high gain DC-DC converter is presented. The proposed converter is based on Ćuk converter, also consists of two inductors, which are charged in parallel by input source and discharged in series. Most dominant benefits of the proposed converter are high voltage gain without using any coupled-inductor and transformer, low voltage stress across switches and simple control system. Therefore, switches with lower voltage level can be used in the proposed converter. Fortunately, these switches have low ON-state resistance 𝐑𝐝𝐬.𝐨𝐧 , which causes decreasing in switch conduction losses. Therefore, the efficiency of the proposed converter is increased. Finally, the principle operation and simulation results of the introduced converter are presented.
