Intelligent RF System for Ultra Low Power Spectrum Sensing with Machine Learning
The crowdedness of the RF spectrum constitutes problems in communication, however it also accommodates large amount of useful information. This information can be used to determine existing signals and operating contexts. However, spectrum condition varies ...
EPFL2023Control Strategy for the Discharge Phase of an Ultra-High Voltage (>7kV) Bi-Directional Flyback Converter Driving Capacitive Actuators
Yves Perriard, Alexis Boegli, Raphaël Johannes Charles Mottet
Dielectric Elastomer Actuators (DEAs) require ultra high voltages in the order of several kilo volts to operate. To supply such voltages, a DC-DC flyback converter topology was selected. One of the main advantage of using such a structure is the possibilit ...
2020Design Optimization of Two-Quadrant High-Current Low-Voltage Power Supply
Drazen Dujic, Émilien Luc Henri Coulinge, Serge Pittet
The high-current delivered by a dedicated power supply is the condicio sine qua non to obtain the strong magnetic field produced by superconducting magnets. The end goal of such power supply is to control the current, very precisely, across this distinctiv ...
2020Design of an external BLDC motor with integrated electronics for 48V on-board power supply
For truck and electric two-wheel applications, the design target is an electric motor with working point in the range of 18-20Nm @ 4000rpm functioning at ambient temperatures from -40°C to 105°C. The design will be based on an existing Sonceboz BLDC motor. ...
2016A 420 mu W, 4 GHz Approximate Zero IF FM-UWB Receiver for Short-Range Communications
A low-power FM-UWB receiver intended for short range communications in wireless sensor networks is presented in this paper. It utilizes an "approximate zero IF" architecture which combines a free-running ring oscillator as the RF LO with a modified delay-l ...
Ieee2016A low-voltage CMOS-compatible time-domain photodetector, device & front end electronics
During the last decades, the usage of silicon photodetectors, both as stand-alone sensor or integrated in arrays, grew tremendously. They are now found in almost any application and any market range, from leisure products to high-end scientific apparatuses ...
