Tuning with Phosphorylcholine Grafts Improves the Physicochemical Properties of PLL/pDNA Nanoparticles at Neutral pH
(2020-02-01)
The improvement of biological properties of polycations is a fundamental step to overcome their limitations as non-viral gene carriers. This work studied the effect of phosphorylcholine (PC) groups on the physicochemical ...
Estudo do conversor cc-ca a quatro fios com capacitor dividido conectado à rede com desequilíbrio de carga
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Elétrica - PPGEECâmpus São Carlos, 2021-06-16)
The three-phase dc-ac converters based on power electronics are the main equipment used to connect renewable sources to the electricity distribution system. The three-phase four-wire distribution system with voltage unbalance ...
Improved Noise Immunity for Two-Sample PLL Applicable to Single-Phase PFCs
Synchronization in a single-phase Power Factor Correction (PFC) is deteriorated, among others, by the combination of the noise introduced by the grid voltage sensing, conducted EMI, the ADC resolution and the sampling ...

Small-signal modelling and stability assessment of phase-locked loops in weak grids
(MDPI AG, 2019)
This paper proposes a low-complexity small signal model for a 3-leg converter connected to a balanced three-phase, three-wire weak grid and synchronised to this grid using a PLL implemented in a synchronous rotating d-q ...
