Abstract


This  paper  deals  with  Analysis of T-Source inverter with PWM Technique for high voltage gain application. The T-source impedance network is newly introduced to overcome the problems of  Z-source inverter. This T-source inverter is similar to Z-source inverter except the use of high frequency low leakage inductance transformer. It has low reactive components in compare with conventional ZSI. This T-source inverter has an ability to perform dc to ac  power conversion and it provides buck -boost operation in a single stage. The traditional inverters cannot provide such feature. Operating principle of T-source inverter is almost same as that of ZSI. All traditional 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 output voltage.
