Evaluation of Quadrature Signal Generation Methods with Reduced Computational Resources for Grid Synchronization of Single-Phase Power Converters through Phase-Locked Loops
(Electronics, 12/2020)Low-cost single-phase grid connected converters require synchronization with the grid voltage to obtain a better response and protection under diverse conditions, such as frequency perturbations and distortion. Phase-locked ... -
Frequency Estimation in DSOGI cells by means of the Teager Energy Operator
(Proceedings of the IEEE Workshop on Computers in Power Electronics, COMPEL, 2022)Second Order Generalized Integrator (SOGI) cells are used for notch filtering due to their simplicity and harmonic rejection capability. SOGI and Dual SOGI (DSOGI) filter cells, combined with Frequency Locked Loops (FLL) ... -
Implementation Oriented Two-Sample Phase Locked Loop for Single-Phase PFCs
(2020 IEEE 21st Workshop on Control and Modeling for Power Electronics, 2020)A low-resource-consuming digital implementation of the Two-Sample (2S) Phase Locked Loop (PLL)for application in low cost single-phase Power Factor Correction (PFC) converters is proposed. The design reduces the sampling ... -
Improved Noise Immunity for Two-Sample PLL Applicable to Single-Phase PFCs
(2021 IEEE 22nd Workshop on Control and Modelling of Power Electronics, COMPEL 2021, 2021)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 ...
