A THREE-PHASE TRANSFORMERLESS T-TYPE- NPC-MLI FOR GRID CONNECTED PV SYSTEMS WITH COMMON-MODE LEAKAGE CURRENT MITIGATION

A Three-Phase Transformerless T-Type- NPC-MLI for Grid Connected PV Systems with Common-Mode Leakage Current Mitigation

DC to AC inverters are the well-known and improved in various kinds photovoltaic (PV) and gird tied systems.However, these inverters are require interfacing transformers to be synchronized with the grid-connected system.Therefore, the system is bulky and not economy.The transformerless inverter (TLI) topologies and its grid interface techniques are

On the myths of indicator species: issues and further consideration in the use of static concepts for ecological applications.

The use of static indicator species, in which species are expected to have a similar sensitivity or tolerance to either Silicone Spray natural or human-induced stressors, does not account for possible shifts in tolerance along natural environmental gradients and between biogeographic regions.Their indicative value may therefore be considered at lea

ISOLATED CLUSTERS OF PF CATALOGUE

The properties of isolated galaxy clusters are discussed.The clusters were found among 1746 PF clusters inclusive 50 and more galaxies in structure field.For Dla Dzieci 19 clusters with distances to the nearest neighbour larger than 68.5 h-1 Mpc we assigned the morphological types of these clusters according to Antlers Abell and Bauts & Morgan.The
