N2 - In this paper, a new single-switch non-isolated dc-dc converter with high-voltage transfer gain and reduced semiconductor voltage stress is proposed. The proposed topology utilize a hybrid switched capacitor technique for providing a high voltage gain without extreme switch dutycycle and yet enabling the use of a lower voltage and RDS-ON MOSFET switch so as to reduce cost, switch conduction and turn-on losses. In addition, the low voltage stress across the diodes allows the use of Schottky rectifiers for alleviating the reverse-recovery current problem, leading to a further reduction in the switching, and conduction losses. The principle of operation and comparison with other high step-up topologies are presented. Simulation and experimental results are also presented to demonstrate the effectiveness of the proposed scheme
