Voltage Clamping Circuits for Large Voltage Step-Down Coupled Inductor Converters
Renewable Energy and Sustainable Development, 2019 Water desalination processes require power converters with large voltage step-down ratios and high efficiencies. Coupled‑inductor (tapped-inductor) circuits can achieve this where the whole inductor carries current during one switch state but only part ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...
