In this paper, one of improved topologies is proposed which called T-source inverter, its special T source network can reduce the use of passive devices, adopting the modified SVPWM control, without complicated coordinate transformation and the sector judgment ,experiment of simulation carried out under the Matlab/Simulink.

The growing demand for energy to promote the research in the field of power transformation, in order to improve the efficiency of the power converter further, many different circuit topologies and control strategies were proposed. In this paper, one of improved topologies is proposed which called T-source inverter, its special T source network can reduce the use of passive devices, adopting the modified SVPWM control, without complicated coordinate transformation and the sector judgment ,experiment of simulation carried out under the Matlab/Simulink.

The Simulation and Research of T Source Inverter Based on Matlab/Simulink and Modified SVPWM Control without Sector Judgment
