Abstract In this paper, a new non-isolated high voltage gain dc/dc converter with low input current ripple is proposed for renewable sources applications. The proposed converter combined SEPIC converter and voltage multiplier cells. In order to achieve high voltage gain, the proposed converter can increase the output voltage level using the voltage multiplier unit. The voltage stress across the semiconductors will be decreased compared to SEPIC, conventional boost converter. Therefore, using only one switch with lower resistance RDS(on), the overall efficiency of the proposed converter is increased significanly. In order to verify the theoretical analysis of the proposed converter and its accurate operation, a 150 W prototype operating at 25 kHz is built and tested.
