High Step-Up Converter With Coupled-Inductor
IEEE Transactions on Power Electronics, 2005In this study, a high step-up converter with a coupled-inductor is investigated. In the proposed strategy, a coupled inductor with a lower-voltage-rated switch is used for raising the voltage gain (whether the switch is turned on or turned off). Moreover, a passive regenerative snubber is utilized for absorbing the energy of stray inductance so that ...

Multiphase Interleaved High Step-Up Converters
2019 IEEE Applied Power Electronics Conference and Exposition (APEC), 2019This paper proposes a family of multiphase interleaved high step-up converters. The multiphase interleaving structure at the input side reduces the input current ripple and increases the power level. The diode-capacitor voltage multiplier stages guarantee a high step-up voltage gain.

High-efficiency, high step-up DC-DC converters
IEEE Transactions on Power Electronics, 2003Many applications call for high step-up DC-DC converters that do not require isolation. Some DC-DC converters can provide high step-up voltage gain, but with the penalty of either an extreme duty ratio or a large amount of circulating energy. DC-DC converters with coupled inductors can provide high voltage gain, but their efficiency is degraded by the ...
