In order to reduce size and cost, high-order passive filters are generally preferred in power
converters to cancel out high-frequency harmonics caused by pulsewidth modulation …

Grid-tied voltage source inverters using LCL filter have been widely adopted in distributed
power generation systems (DPGSs). As high-order LCL filters contain multiple resonant …

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 introduction of microgrids in distribution networks based on power electronics facilitates
the use of renewable energy resources, distributed generation (DG) and storage systems …

In this paper, a new mode of operation has been introduced for packed U-cell (PUC)
inverter. A sensor-less voltage control based on redundant switching states is designed for …

The main purpose of developing microgrids (MGs) is to facilitate the integration of renewable
energy sources (RESs) into the power grid. RESs are normally connected to the grid via …

Harmonic stability problems caused by the resonance of high-order filters in power
electronic systems are ever increasing. The use of passive damping does provide a robust …

Grid-connected converters employ LCL-filters, instead of simple inductors, because they
allow lower inductances while reducing cost and size. Active damping, without dissipative …

LCL-filters are preferred over conventional L-filters for grid-connected voltage-source
inverters (VSIs) due to their superior harmonic attenuation and smaller filter size and weight …

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 …
