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

Impedance-source networks cover the entire spectrum of electric power conversion
applications (dc-dc, dc-ac, ac-dc, ac-ac) controlled and modulated by different modulation …

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

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 …

One of the most promising power electronics converter topologies is the Z-source inverter
(ZSI). The ZSI is an emerging topology for power electronics dc-ac converters with …

Finite-control-set model-predictive control (FCS-MPC) requires a large amount of
calculation, which is an obstacle for its application. However, compared with the classical …

The voltage-fed Z-source inverter/quasi-Z-source inverter (qZSI) has been presented
suitable for photovoltaic (PV) applications mainly because of its single-stage buck and boost …

Leakage current minimization is one of the most important considerations in transformerless
photovoltaic (PV) inverters. In the past, various transformerless PV inverter topologies have …

This paper proposes a new single-phase transformerless photovoltaic (PV) inverter for grid-
tied PV systems. The topology is derived from the concept of a charge pump circuit in order …

The quasi-Z-source inverter (qZSI) with battery operation can balance the stochastic
fluctuations of photovoltaic (PV) power injected to the grid/load, but its existing topology has …
