Abstract

Namen magistrskega dela je modifikacija pretvornika navzgor s preklopnimi kondenzatorji z namenom povečanja izkoristka. Uporaba pretvornika je mišljena v sistemih pridobivanja energije s termoelektričnimi elementi. Predstavljen je model in simulacije modificiranega pretvornika, podana je tudi primerjava med osnovnim in modificiranim vezjem. Predstavljene so ugotovitve in problemi pri delovanju modificiranega pretvornika navzgor s preklopnimi kondenzatorji. Predstavljeno je odprto-zančno delovanje pretvornika, ter izmerjene statične karakteristike pri različnih bremenskih upornostih. Implementirana je kaskadna regulacija brez linearizacijskih algoritmov, zaradi kompleksnosti in računske zahtevnosti le-teh.

Secondary title: Optimization, modelling and control of a switched capacitor boost converter
Secondary abstract: The purpose of this master thesis is to improve the efficiency of the switched-capacitor boost converter. The converter is intended to be used in an energy harvesting system that uses thermoelectric generators. Mathematical model and simulations of the converter, along with the comparison between the basic and modified circuit are presented in this thesis. The findings and problems in the operation of the modified switched-capacitor boost converter are also presented. The operation of the converter, as well as the measured static characteristics are presented. A cascade control algorithm is implemented, although without the linearization algorithms due to the complexity and microcontroller performance requirements of these algorithms.
