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 ...
