This paper deals with performance of three and five level grid-connected T-type inverters. T-Type structure requires fewer power devices than Neutral-Point-Clamped and FlyingCapacitor inverters for the same power level. First, mathematical model of grid connected T-Type inverters is demonstrated. The PI controller is used to control the d-axis and q-axis currents, respectively. The sine Pulse Width Modulation (PWM) technique is used to control the MOSFET switches. The simulation of the complete system has been performed on MATLAB/Simulink.
