The phase-locked loops (PLLs) are probably the most widely used synchronization
technique in grid-connected applications. The main challenge that is associated with the …

This paper deals with the improvement of the transient response and harmonic,
subharmonic, and dc-offset voltage rejection capability of a grid voltage sequence detection …

The increasing number of distributed power generation systems (DPGSs) is changing the
traditional organization of the electrical network. An important part of these DPGSs is based …

This study deals with the analysis and implementation of compensation algorithms applied
to a shunt active power filter, which uses three single‐phase full‐bridge converters sharing …

In this paper, the analysis of space vector modulation of a three-phase/wire/level Vienna
rectifier is conducted, according to which the implementation of the equivalent carrier-based …

This paper applies the adaptive gradient descent method to the second-order generalized
integrator (SOGI) filter in order to find an online estimation algorithm for the grid frequency …

This paper proposes a new three-phase software phase-locked loop (PLL) that operates fast
and accurately in unbalanced, polluted, and frequency deviating circumstances. The …

Primitive grid synchronization systems of power converters were based on a zero-crossing
detection (ZCD) algorithm, which is an open-loop synchronization (OLS) system. ZCD …

This paper proposes a fast and robust phase estimation algorithm (PEA), a counterpart of
the phase-locked loop (PLL), for heavily distorted grid conditions. The PEA, named as the …

In this paper, an adaptive filter, based on a third-order generalized integrator, is proposed to
estimate all the parameters of a biased sinusoid. The averaging theory is used to prove that …
