High-efficiency DC/DC converter with high voltage gain [PDF]
IEE Proceedings - Electric Power Applications, 2005 A high-efficiency converter with high voltage gain applied to a step-up power conversion is presented. In the proposed strategy, a high magnetising current charges the primary winding of the coupled inductor, and the clamped capacitor is discharged to the auxiliary capacitor when the switch is turned on.

High-Voltage Gain Quasi-SEPIC DC–DC Converter [PDF]
IEEE Journal of Emerging and Selected Topics in Power Electronics, 2019 This paper proposes a modified coupled-inductor SEPIC dc-dc converter for high voltage gain (2 < G < 10) applications. It utilizes the same components as the conventional SEPIC converter with an additional diode. The voltage stress on the switch is minimal, which helps the designer to select a low voltage and low RDS-on MOSFET, resulting in a ...
