Control of three-phase PWM boost rectifiers using proportional-resonant controllers
(2018-06-25)
Voltage-oriented vector control (VOC) using proportional-integral controllers is an attractive control method for three-phase PWM rectifiers, due to relative ease of implementation, being one of the most used methods. ...
Proportional resonant controller and lcl filter design for single phase grid connected pv micro inverters
(Institute of Electrical and Electronics Engineers Power and Energy Society, 2018-09-18)

Resonant current controller with enhanced transient response for grid-tied inverters
(Institute of Electrical and Electronics Engineers, 2018-04-08)
This paper highlights the limitations of the dynamic response of a grid-tied inverter connected through an inductor $L$ when it is controlled using a proportional+resonant controller. Then, a new resonant current controller ...
Design approach of discrete-time resonant controllers for uninterruptible power supply applications through frequency response analysis
(Institution of Engineering and Technology, 2016-12)
A new methodology to design discrete-time multiple resonant controllers for single-phase uninterruptible power supply inverters is proposed in this study. This methodology is based on classical linear tools and consists ...
Proportional Resonant Controller for a 27-Level Asymmetric Multilevel STATCOM
(2017)
