This paper presents a new pulse-width modulation that allows the three-phase Z-source inverter photovoltaic system operate without transformer and assuring very low leakage currents. Furthermore, a proper switching pattern is chosen in order to assure a reduced number of commutations, leading to reduced switching losses in the inverter. Experimental results of the three-phase Z-source inverter connected...
The increasing utilization of photovoltaic (PV) solar systems in distributed (or dispersed) generation systems imposes new requirements for the operation and management of the distribution grid, especially when high penetration levels are achieved. Under this scenario, the power electronics technology plays a vital role in managing an effective grid integration of the PV system, since it is subject...
