Received May 11, 2013 Revised July 10, 2013 Accepted July 28, 2013 This paper cite comparative performance characteristics of Z-Source inverter fed IM drives with mostly used VSI & CSI fed IM drives. ZSI has both voltages buck and boost capabilities as they allow inverters to be operated in the shoot through state. It employs an exclusive Z-Source network (LC component) to dc-link the main inve...

in recent years, there has been a fast growth in wind energy conversion system (wecs). there are two general types of wind turbines in wecs: fixed speed wind turbines and varying speed wind turbines.permanent magnet synchronous generator (pmsg) is one of the most attractive generators for the varying speed turbine wecs.in this paper, a fuzzy controller is proposed to control the current source ...

This paper presents a novel control scheme for three-phase quasi-z source inverter (qZSI) using capacitor voltage and input current-based sinusoidal pulse width modulation (SPWM) technique. The proposed combines the advantages of both qZSI SPWM techniques to achieve improved performance. technique utilizes signal, which is compared with high-frequency triangular carrier wave two shoot-through (...
