Design of an impedance source converter for high-performance PV power system applications

Abstract

This project describes the principles of impedance-source/quasi-impedancesource inverters, which have the main particularity of being able to operate as voltage-boost inverters. Therefore, the appropriate circuit analysis and modelling are presented, together with a study of the control methods applicable to this type of inverters. The design of passive components to meet electrical requirements is also presented. Theoretical results are validated with both circuit simulations and experimental tests.
