An Interleaved Soft Switching High Step-Up Converter With Low Input Current Ripple and High Efficiency

open access: yesIEEE Access, 2019
This paper proposes a high step-up low-ripple dc-dc converter for sustainable energy conversion. A high step-up voltage gain is obtained with an input-current doubler and a switched-capacitor circuit rather than having to use a transformer with a high ...
