Uninterruptible Power Supplies (UPS’s) are designed to provide emergency power when the main power source fails. To avoid this impact and to protect effectively the loads, one solution is to provide a redundant loading ...

A foreground calibration algorithm is proposed to digitally self-calibrate a switched-capacitor (SC), pipelined, analog-to-digital converter (ADC). Static errors resulting from capacitor mismatch, charge transfer loss (from ...

This thesis proposes the analysis of two single-stage high-frequency isolated converters suited for grid-tied applications. Firstly, a new modulation strategy to the bidirectional flyback converter with differential output ...

This thesis presents the study and characterization of organic light-emitting diodes (OLEDs) with the proposal of obtaining an equivalent model that is useful in the OLED driver design and in lighting systems projects. ...

In this article, the model of an unbalanced bipolar micro-network in direct current is proposed. The results of a set of maneuvers are presented which aims to reduce voltage unbalance and therefore minimize power losses ...
