Adapted SVPWM for T-source inverter for renewable energy system

The peak need of alternative energy resource to satisfy the demand in energy also elicited the research in the area of power converters. The Z-Source Converter which can be used for both current and voltage sources is used for both buck and boost operation in various renewable energy applications like wind and solar energy conversion system. To improve the operation of the converter further, different topologies are being proposed. The T-source inverter is the modified form of Z-source inverter with the reduced number of passive components. The paper proposes the modified space vector pulse width modulation for the modified Z-source inverter or T-source inverter. The performance of the T-source inverter is analyzed based on the gate pulse fed by the adapted space vector pulse width modulation generator. The system level simulation is performed using MATLAB/SIMULINK software.
