Appropriate Control Methods for PWM ac-to-dc Converters Applied in Active Line-Conditioning

Abstract

The paper investigates the performances of a PWM AC-to-DC converter operating with the help of new control strategies, implemented so that the conditioning of the utilities may become possible. It is discussed the idea to use the PWM DC converters as power conditioner equipments too. The new concept of the AC line-conditioning with the help of the DC converters the DC converters is introduced and systematically classified. Appropriate control strategies are studied with the purpose to apply the active line conditioning. Corresponding Matlab/Simulink structures are developed. The result of the simulations, depicted in the paper proves the line-conditioning capabilities of the investigated converter
