Abstract This project presents a PMW controller to control the output current and voltage for
a Z-Source single phase inverter. The model scheme is developed and simulated in Matlab
Simulink software environment. The Z-Source inverter is special type of inverter that provide
the voltage boost capability in which it results with an output voltage greater than the input DC
voltage and that cannot be obtained using the traditional inverter. Using the PMW controller,
the inverter reference tracking performance can be enhanced. Simulation study of Simulink
software is presented. The results show the Matlab Simulink software achieves very good
results with a good tracking capability for the reference values of both current and voltage.
Besides, it maintains a small error signal which makes it a preference controller compared to
the other traditional controllers
