Power factor correction and load balancing in three-phase distribution systems
This paper deals with the different methods for compensating unbalanced three phase loads. Compensation of grounded, ungrounded star connected and delta connected three phase unbalanced load has been carried out. Three ...
Comparison of PI, VSC and energy balance controller for single phase active filter control
This paper presents a comparison among proportional-integral, variable structure voltage controller and energy balance controller for the control of single phase active filter. Proportional-integral (PI) and variable ...
A review of single-phase improved power quality AC-DC converters
Solid-state switch-mode rectification converters have reached a matured level for improving power quality in terms of power-factor correction (PFC), reduced total harmonic distortion at input AC mains and precisely regulated ...
Fuzzy supervisory controller for improved voltage dynamics in power factor corrected converter
This paper investigates the performance of a Fuzzy Supervisory Controller (FSC) in control of power converters. An FSC module is added to a conventional narrow bandwidth voltage regulator in a Power Factor Corrected (PFC) ...
A novel DC bus voltage sensorless PFC rectifier with improved voltage dynamics
A novel DC bus voltage estimation algorithm with inherent cancellation of feedback voltage ripple is presented in this work. Design issues are discussed and simulation results are presented. Apart from reduction of output ...
A simple fast voltage controller for single-phase PFC converters
In this work a simple and robust voltage controller is proposed to improve voltage dynamics in the power factor corrected (PFC) converters. The proposed controller eliminates twice the line frequency ripples from the voltage ...
