A high voltage gain modified SEPIC converter is proposed in this paper. This proposed converter has manyadvantages i.e., high output voltage, lower voltage stress, high efficiency, voltage gain is high without anycoupled inductor and transformer, continuous input current. Thus, there is no overshoot voltage at turn-offprocess for switches. By using single switches, the CCM mode operation can be easily controlled by thisconverter, so control system is simple and also wide output values is obtained only by modifying the dutycycle. This modified converter has lower components than conventional converter. The operating modes anddesign of modified converter are discussed. The output power of this converter is 6 watts. By this converter,this converter capable of developing the two and half times of input voltage. The PV system also used thisconverter to develop high voltage gain. This high voltage gain is achieved by using MATLAB/SIMULIMKplatform.
