PV based QZS Inverter with Improved Space Vector Modulation Technique

Since the ZSI was first presented in 2003, numerous research initiatives have been formed to improve its performance, and major changes have been made since then. A change to the ZSI’s framework, such as changing its topology as well as its modulation scheme, are among them. The existing modulation system has several drawbacks including the need for extra reference signals and at the time of elementary duration the current is high along with the higher number of switching. This paper work demonstrates an enhanced modulation technique to ameliorate the functioning of three-phase QZS inverter and related topologies. An enhanced space vector modulation approach solves the problem of a greater number of switch commutations throughout the basic cycle, making it easier to create gate signals with only three reference signals and one commutation at a time.
