Multi-level topologies allow the use of 900 V and 650 V SiC and GaN devices in 1500 V PV systems . In the literature, efficiencies of 99 % for PV inverters with SiC devices are reported, even if the higher cost is actually a limit for practical industrial use .

How efficient are PV inverters with sic devices?

In the literature, efficiencies of 99 % for PV inverters with SiC devices are reported, even if the higher cost is actually a limit for practical industrial use . In Table 2 a comparison of selected topologies, each one representing each described families is carried out.

What is a safety feature of a PV inverter?

Islanding is the process in which the PV system continues to supply power to the local load even though the power grid is cutoff . A safety feature is to detect islanding condition and disable PV inverters to get rid of the hazardous conditions. The function of inverter is commonly referred to as the anti-islanding.

What is three-level neutral-point-clamped voltage source inverter (3l-npc)?

Recently, Three-Level Neutral-Point-Clamped Voltage Source Inverter (3L-NPC for abbreviation) has gained attention in PV application because of several advantages and essential features (see Fig. 1). The main advantage of this topology for TRL application is that the midpoint of the dc-link is connected to the grid neutral.
