Analysis of T-Source Inverter with Simple Boost Control Technique for Improving Voltage Gain
The small signal model of the new three-phase Z-source inverter z source inverter thesis derived and the transfer function of system is given. The effect on right-hand-plane zero caused by different parameters is analyzed based on loot-locus analyses.
The present closed loop control strategy of Z-source inverter is complex and not always stable.
A new feed-forward of input plus feedback of peak output control strategy is proposed, and the control of DC-link and z source inverter thesis stage is decoupling.
This control strategy is simple and stable, and there is no steady-state error in ac output. The analysis is verified by experimental results.
The system volume and cost can be reduced and the reliability can be improved.
The parameters design rule is given. A prototype is built on and the experimental results are given.
Analysis and simulation of z-source inverter control methods
The small signal model of the new three-phase Z-source inverter is derived and the transfer function of system is given.
The effect on right-hand-plane zero caused by different parameters is analyzed based z source inverter thesis loot-locus analyses. The present closed loop control strategy of Z-source inverter is complex and not always stable. As with a z source inverter thesis ZSI, the TSI can handle shoot through states when both switches in the same phase leg are turned on.
The T-network is used instead of the LCnetwork for boosting the output voltage by inserting shoot through states in the PWM.
Research on Z-source Inverter - PhD thesis - Dissertation
T-source Inverter operating principle same as that of conventional ZSI. TSI operate in Shoot through mode and Non shoot through mode. In shootthrough mode of operation, the output voltage is boosted.
In conventional z source inverter thesis VSI, it is not possible. Normally Z-source inverter requires two inductance and two capacitance but T-source inverter requires a very low leakage inductance transformer which should be made with high precision.

In such a way, the number of passive elements is reduced because only the transformer and the capacitor are needed z source inverter thesis that total volume of the system can be minimized. TSI can handle shoot through states when both switches in the same phase leg are turned on.
The T-network is used instead z source inverter thesis the LC-network for boosting the output voltage by inserting shoot through states in the PWM. General Description The new impedance network has been introduced to overcome the problems of the traditional V-source and Isource inverters.
The power source can be either in the form of voltage source or current source.

Ths impedance network reqiures two inductors and two capacitors connected to each other  ZSI provides a single-stage voltage buck-boost operation. Unique LC impedance network significantly improves the performance of the inverter. It allows shoot-through states of the inverter legs during boost operation as well open circuits of z source inverter thesis legs during normal buck operation.
In some applications the efficiency of Z-source inverter lower than conventional two-stage buck-boost systems?
