A MODIFIED BOOST DC-AC INVERTER USING Z-SOURCE: OPERATION, ANALYSIS, CONTROL AND EXPERIMENTATION
inductor, capacitor, ripple voltage
This paper proposes a new voltage source inverter referred to as a modified boost inverter using z-source. The main attribute of this new inverter topology is the fact that it generates that an AC voltage larger than the DC input one, depending on the instantaneous duty cycle. The conventional dc to ac boost converter has resulted in several voltage ripples in load. In order to avoid these ripples, Z-source inverter is introduced between the source and the inverter circuit. The proposed control strategy achieves a very high reliable performance with fewer ripples than the conventional boost inverter. The main advantages are low cost, less number of switches used, compact size and reduce the power processing stages into single stage.
