Analysis and Design of a Low Power Capacitively Isolated Power Convert
Research Groups microelettronica
Thesis type DESIGN AND SIMULATIONS, EXPERIMENTAL AND SIMULATION
Description While inductive coupling is widely exploited in electronic power converters for wireless power transfer, capacitive coupling is much less explored. This is mainly due to the fact that capacitively-coupled converters have stringent constraints on component values and switching frequency which are difficult to be met by standard power semiconductor technology. In recent years, the development of new power semiconductor technologies (e.g. GaN, SiC) has radically changed the situation and has raised an increasing interest towards capacitive power coupling as an alternative to traditional inductive coupling as a mean to achieve higher efficiency and power density.
The thesis targets the analysis and the design of a capacitively coupled power converter, fully exploring the advantages and potential limitations of this approach.
The thesis work will be organized as follows:
1) Operating principle
2) Capacitive Power Transfer Systems: advantages and disadvantages
3) Challenges of a Capacitive Power Transfer System
4) Analysis and Design Methodology
5) Converter optimization under load variations and passive component tollerances
6) Design of capactively coupled AC – DC converter ( 60/70W power rating)
7) Choice of semiconductors and passive components. Design criteria and costs.
8) Performance analysis
Required skills Power electronics, Circuit Theory
