Power quality is a pressing concern and of the utmost importance for advanced and high-
tech equipment in particular, whose performance relies heavily on the supply's quality …

Recently, several advanced phase-locked loop (PLL) techniques have been proposed for
single-phase applications. Among these, the Park-PLL and the second-order-generalized …

In the past five years substantial amounts of rooftop photovoltaic (PV) generation have been
installed across the low voltage distribution networks. These networks often have design …

One of the most important aspects for the proper operation of the single-phase grid-tied
power-conditioning systems is the synchronization with the utility grid. Among various …

Voltage sag is a common and undesirable power quality phenomenon in the distribution
systems which puts sensitive loads under the risk. An effective solution to mitigate this …

A dynamic voltage restorer (DVR) to compensate deep voltage sags and harmonics is
proposed. The DVR consists of shunt and series converters connected back-to-back through …

This paper presents a new open-loop architecture for three-phase grid synchronization
based on moving average and predictive filters, where accurate measurements of phase …

In this paper, an improved control scheme is proposed to improve the voltage quality of
sensitive loads using dynamic voltage restorer. The existing control strategies either put …

The cutoff frequency of the output LC filters of PWM inverters limits the control bandwidth of
the converter system while it attenuates voltage ripples that are caused by inverter switching …

This paper proposes a new fault current limiting dynamic voltage restorer (FCL-DVR)
concept. The new topology uses a crowbar bidirectional thyristor switch across the output …
