Analysis of T-Source Inverter with Simple Boost Control Technique for Improving Voltage Gain

Abstract

This paper deals with Analysis of T-source Inverter with simple boost control technique for improving voltage gain. T-source impedance network is newly invented to overcome the drawbacks of Z-source inverter. T-Source inverter has high frequency low leakage inductance transformer and one capacitance, this is the main difference from Z-source inverter . It has low reactive components in compare with conventional ZSI. The Tsource network has an ability to perform dc to ac power conversion and it provides buck boost operation in a single stage but the traditional inverter cannot provide such feature. Operating principle of T-source inverter is almost same as that of ZSI. All PWM methods can be used to control T-source inverter. The utilization of shoot-through switching state is enhanced in T-Source inverter which helps in the unique usage of buck-boost feature to the inverter. It is recommended that to maintain the constant voltage in the input side to get the appropriate voltage in the output side.
