Broadband Zero-Bias RF Field-Effect Rectifiers Based on AlGaN/GaN Nanowires

Elison de Nazareth Matioli, Giovanni Santoruvo

Microwave zero-bias rectifiers are fast devices capable of rectifying RF signals without applied bias, which have applications ranging from RF power detection to THz imaging systems. Here we present gated nanowire field-effect rectifiers (NW-FERs) fabricat ...

Input-Series and Output-Series High Voltage Converter with Active Balancing Circuit for N-1 Operation

Alfred Rufer, Tiago Alexandre Nabais Lima

An input-series/output-series converter dedicated to high power applications is presented. The converter is composed of plural MF transformers based on DC-DC sub-converters. The series connection allows reaching input-voltage levels in the range of several ...

Ieee2016

The use of gas turbines in the power generation industry has been increasing. Their demand represents more than 50% of the world market of thermal power plants. Electric power generators using gas turbines as power sources are connected to the turbines thr ...

Brown adipose fat tissue of a mouse dissipates the animal’s energy in the form of heat. Chronically recording the temperature of this tissue helps biologists to study the metabolism of the animal and gain new insights about the obesity in humans. Such temp ...

EPFL2014

Single-phase active rectifiers exhibit an inherent strong second-order current harmonic on their DC-link. The latter is often undesirable from a load point of view and is therefore chosen to be eliminated. A common method is the use of a resonant passive L ...
