In this paper, an alternative non-isolated DC-DC converter with a high voltage boosting capability is proposed. Two inductors are

used and one of them has its flux linkage increases during its charging period to achieve a high step-up voltage gain. Among the

three integrated capacitors, one portrays the partial characteristic of the switched-capacitor technique, while the other two

are connected in series across the load. With the two switches controlled using the same duty cycle, the proposed

topology demonstrates the merits of a higher and wider range of step-up voltage gain when compared with recent topologies. In

addition, a reduction in loss is induced and a higher efficiency is ensured with all the voltage stresses constrained within the output

voltage. Operation of the proposed converter is analyzed and validated through experimental results obtained with a prototype.
