An Optimizing Methodology of ZSI with Suitable PWM Control Techniques
K. Supraja | K. Suresh 
Abstract: This paper presents a novel 3-phase Z-source inverter with six switches. The proposed system have different PWM techniques i. e. , simple boost, maximum boost, maximum constant boost, modified space vector PWM etc. , are reviewed and compared for Z-source inverter or traditional Z-source inverter. The comparison shows that the maximum constant boost control is the most suitable PWM control method for any ZSI topology. A model of Z-source inverter is built in MATLAB/SIMULINK and its performance is analyzed with different PWM control techniques. This project presents the performance characteristics of ZSI with reduced THD and high fundamental component. Simulation results prove the desired features and feasibility of the proposed system.
