Low power systems

This thesis presents a method of data analysis of a multichannel spectroscopic data acquisition system for a large segmented detector of reactor antineutrinos. The method is described, and two implementations are presented. One for PMT based spectrometer for the DANSS detector, built by...

Moldaschl, Jan
Impulsní výkonové síťové nabíjecí a napájecí zdroje

A massive using of switched mode power supplies causes a high harmonic pollution of the line current. The distortion is significant due to a non-linear behaviour of the rectifying diodes and bulky input capacitor of SMPSs. The behaviour causes short spikes of the line current,...

Pušman, Lukáš
Embeded systémy pro lokalizaci a určování polohy

In this thesis a design of a railway-vehicle localization system based on the inertial navigation and specific track-segment detection is described. The system offers an alternative to the traditional solution of the navigation task based on the Kalman filter and it uses primarily ...
