Summary:Most of the electrical devices requires converter or inverters in its operation to convert ac to dc voltage and vice-versa. This paper deals with the comparison of Z-source inverter, T-source inverter and improved T-source inverter. This type of inverters has an impedance network after its source unlike traditional voltage and current source inverters which helps in boost capability. They work on two modes of operation - shoot through mode and non-shoot through mode. T-source inverter results in high boost capability than Z-source inverter whereas improved T-source inverter has high boost capability and low current ripple than T-source inverter due to modifications in its topology. Sinusoidal pulse width modulation is used as controller and helps in generation of pulses to the switches. Moreover improved T-source results in less THD and it can be concluded that improved T-source inverter has better characteristics than conventional inverters. This paper presents the operating principles, analysis and simulation results, and compares them with those of the conventional Z-source inverter with T-source and improved T-source inverter. The simulation of various inverter topologies is done in MATLAB and results are shown.
