In distribution systems, in order to diminish power losses and keep voltage profiles within acceptable limits, network reconfiguration and capacitor placement are commonly used. In this paper, the Hybrid Shuffled Frog Leaping Algorithm (HSFLA) is used to optimize balanced and unbalanced radial distribution systems by means of a network reconfiguration and capacitor placement. High accuracy and ...

The performance of traditional continuous-time (CT) delta-sigma analog-to-digital converters (ADCs) is limited by their large sensitivity to feedback pulse-width variations caused by clock jitter in their feedback digital-to-analog converters (DACs). To mitigate that effect, we propose a modified switched-capacitor (SC) feedback DAC technique, with a variable switched series resistor (SR). The ...

This paper presents a data acquisition solution using a RISC type microcontroller with very few components around, taking advantage of the ratiometric functioning of the load cells. The need of thermally stable circuits is minimized through the use of the same amplification chain for both signal and reference. The amplification and filtering are done trough switched-capacitor techniques control...
