T-Source inverter is a single stage power converter which can be used as a cost effective alternative for Z-source inverter. Dynamic modeling and analysis of T-source inverter (TSI) is vital for the determination of system limits, components selection for T-shape impedance network and controller design. A novel dynamic model of TSI in continuous conduction mode using the state space approach has been derived here. The derived model has been analyzed by introducing a disturbance in both the load and source side of the TSI. The stability, limitations and component selection of TSI have been done using pole-zero map and frequency response plots. The mathematical models are verified by Matlab / Simulink and experimental results.


Key words: T-Source Inverter, dynamic model, small signal model, state space model, continuous conduction mode.
