Abstract Most coupled inductor‐based step‐up DC–DC converters encounter a significant voltage overshoot on their power switch due to the leakage inductance of the coupled inductor. So, they need additional bulky snubber circuits or a sophistica

Piezoelectric resonators promise to increase dc-dc converter power density by replacing inductive components. However, piezoelectric resonators are not direct circuit level replacements for inductors, requiring new topologies. In this paper, we prese
