ABSTRACT In this paper, a new non-isolated Interleaved dc/dc converter with high-voltage conversion ratio is presented. The proposed converter combined with interleaved converter techniques and voltage multiplier cell (diode/capacitor/inductor). The voltage stress across the power semiconductors (power MOSFETs/diodes) is decreased compared to SEPIC, conventional boost converter. The low normalized stress causes to using the low rating semiconductors. In fact, the overall efficiency of the proposed converter will be increased by using MOSFETs with lower resistance RDS(on) and lower ranges for power diodes. To confirm the accuracy theoretical analysis of the proposed converter and operation converter, a laboratory prototype in about 190 W with operating at 40 kHz is built and tested.
