Multilevel Z-source inverters have been proposed as a solution for HV applications. This type of inverters decreases the Total Harmonic Distortion (THD) and has a good performance for different applications such as Flexible AC Transmission Systems, power quality improvement and connecting renewable energy resources to the network. This paper compares several alternative carrier disposition PWM strategies for a five-level Z-source diode-clamped inverter. These strategies are simulated in MATLAB/Simulink. The simulation results illustrate that using Phase Disposition (PD) method, the voltage THD decreases considerably. Also, Alternative Phase Opposition Disposition (APOD) method increases the voltage magnitude more than PD method. Both methods can be effectively used for connecting renewable energy sources to the power grid.
