Multilevel converters have been under research and development for more than three
decades and have found successful industrial application. However, this is still a technology …

Power delivered by a Photovoltaic (PV) cell reduces significantly due to non-uniform
irradiance. Consequently, in the case of PV module or array, the generated output power get …

Single-phase voltage source transformerless inverters have been developed for many years
and have been successful commercial applications in the distributed photovoltaic (PV) grid …

In this paper, the idea of operating an inverter to mimic a synchronous generator (SG) is
motivated and developed. We call the inverters that are operated in this way …

Integrating renewable energy and other distributed energy sources into smart grids, often via
power inverters, is arguably the largest “new frontier” for smart grid advancements. Inverters …

The main design objective of photovoltaic (PV) systems has been, for a long time, to extract
the maximum power from the PV array and inject it into the ac grid. Therefore, the maximum …

Partial shading in photovoltaic (PV) arrays renders conventional maximum power point
tracking (MPPT) techniques ineffective. The reduced efficiency of shaded PV arrays is a …

Multilevel cascaded H-bridge converters are promising candidates for large-scale
photovoltaic power plants. They allow direct connection to medium-voltage distribution …

This paper presents a single-phase cascaded H-bridge converter for a grid-connected
photovoltaic (PV) application. The multilevel topology consists of several H-bridge cells …

This paper presents an energy-balance control strategy for a cascaded single-phase grid-
connected H-bridge multilevel inverter linking n independent photovoltaic (PV) arrays to the …
