Study of the Voltage Source converter and different control schemes

Abstract

This project is focused on the study of a specific kind of DC to AC or AC to DC converter, named voltage ource converter (VSC), but specifically on the three-phase and two level version. On the one hand, the fundamental structure and the operation principle will be explained more in depth. On the other hand, the Different applications of this converter will be seen with more emphasis through simulation. For that purpose, this work is comprised by the following steps: 1. Study of the VSC structure and operating principle, which will be the main component of our systems, and study of the medium frequency transformer. 2. Study and simulation of the different control strategies. 3. Conclusions from the different simulated systems and control strategies, and review of the different features of the VSC and the transformer seen during the project. The diferent models and simulations are done using Matlab, Simulink and Simpowersystems.
