Abstract :
The paper compares three PWM control methods on a single-phase Z-source inverter (ZSI); traditional, simple-boost (SB-PWM), and modified-reference (MR-PWM). A model of the inverter in an open-loop system was built in Matlab/Simulink. The methods and their modulation indices were analyzed against two design parameters (dc-input voltage and switching frequency), the analysis basing determination of the Z-source inverter´s performance.
