High‐efficiency high step‐up PWM resonant converter
Electronics Letters, 2015 A novel high‐efficiency high step‐up pulse‐width modulation (PWM) resonant converter is proposed. It achieves high‐voltage step‐up by connecting the outputs of the boost converter cell and the isolated single‐ended PWM resonant converter cell in series, and high efficiency by zero current switching for the diode on the secondary side of the transformer

High‐step‐up enhanced super‐lift converter
IET Power Electronics, 2020 This study proposes a new high step‐up DC–DC converter based on a novel super‐lift structure and coupled inductor. The energy stored in the leakage inductance of the coupled inductor is recovered to the converter output, which leads to a snubber‐less operation and consequently a fewer‐component, lower‐cost and more‐efficient converter.
