This work proposes a high step-up interleaved dc/dc topology utilizing a VM (voltage multiplier) cell suitable for PV applications. The VM cells D/C (Diode/Cap.) are cascaded among the phases to approach a high voltage gain. Besides, the voltage converting ratio of the presented structure can be improved by extending the VM cells and it also leads to drop in the normalized voltage stress throug...

In this work, a non-isolated high step up DC-DC converter using coupled inductor and voltage multiplier cell is proposed. The proposed converter conversion ratio is efficiently extended by using a coupled inductor. An interleaved configuration of two diode-capacitor cells is applied to step up the voltage conversion ratio and decrease the voltage stress across the switches. Also, in the suggest...

In this paper, a high voltage gain non-isolated three-port converter with three-winding coupled inductor is proposed for renewable energy system. By implementing cascoded structure where photovoltaic (PV) source stacked on top of battery source, the output can be achieved reasonable duty cycle, resulting in higher efficiency when both sources provide to load. Furthermore, only three power switc...

In this paper, a new type of interleaved high step-up converter including coupled inductor is proposed. The proposed has an configuration on the input side to reduce ripple current and increase power level. Moreover, stacked structure output provides input/output (I/O) voltage gain. addition, can avoid extreme duty cycle, causing larger conduction losses, by combining lossless clamp circuit wit...
