Improved Virtual Flux-Direct Power Control for PWM Rectifier Based on Second-Order Generalized Integrators

, 2020
The AC-DC conversion system in the power system use generally the diode-bridge based rectifiers that cannot be reversible and causes high current distortion. Besides, they reduce the power factor and energy quality.

A Novel Design Method for SOGI-PLL for Minimum Settling Time and Low Unit Vector Distortion

, 2013
Phase-locked loops (PLLs) are necessary in grid connected systems to obtain information about the frequency, amplitude and phase of the grid voltage. In stationary reference frame control, the unit vectors of PLLs are used for reference generation. It is

Reduced order generalized integrators with phase compensation for three-phase active power filter

, 2017
Current regulation is a critical issue for the stable operation of three-phase active power filters (APF). The challenge of the current controller lies in how to track the high slew rate reference with zero steady-state error in a fast and accurate way ...
