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.
