Quasi Z-Source Based Voltage Control in Distributed Power Generation

Amrita Mariam Varghese, Sheela Joseph, Elizabeth Paul

This paper presents a topology for voltage step-up without the use of a converter for local electric power generation.The proposed topology contain a voltage-fed quasi-Z-source inverter on primary side, a single-phase isolation transformer, and a voltage doubler rectifier (VDR) and a single phase inverter. This paper describes the operation principles of the proposed topologies and its modelling. The performance of the topology is studied in a MATLAB/SIMULINK R2010a environment and the results are analysed.
