High-efficiency bidirectional dc–dc converter with high-voltage gain
IET Power Electronics, 2012 The aim of this study is to develop a high-efficiency bidirectional dc-dc converter for a power storage system. The proposed converter can boost the voltage of an energy-storage module (e.g. battery) to a high-voltage-side dc bus for the load demand. When the high-voltage-side dc bus has excess energy, this energy-storage module can be charged by the ...

DC–DC Boost Converter With a Wide Input Range and High Voltage Gain for Fuel Cell Vehicles
IEEE transactions on power electronics, 2019 In fuel cell vehicles, the output voltage of the fuel cell source is typically much lower than the voltage required by the dc bus, and also this output voltage drops significantly as the output current increases.

Detection of liquid xenon scintillation light with a Silicon Photomultiplier [PDF]
, 2005 We have studied the feasibility of a silicon photomultiplier (SiPM) to detect liquid xenon (LXe) scintillation light. The SiPM was operated inside a small volume of pure LXe, at -95 degree Celsius, irradiated with an internal Am-241 alpha source.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Asymptomatic infection poses a significant risk for children undergoing hematopoietic stem cell transplantation (HSCT). Pre‐transplant surveillance computed tomography (CT) is commonly used to identify occult infection, though its diagnostic yield remains uncertain.

Transformerless high voltage gain Y-source converter with reduced switch stress
e-Prime: Advances in Electrical Engineering, Electronics and EnergyThis paper introduces a novel Y-source converter, which utilises a three winding coupled inductor and a switched inductor boost module. In contrast to the conventional layout, the Y source converter has a repositioning of the switch from the load side to
