document: Novel line conditioner with voltage up/down capability In this paper , a novel pulsewidth-modulated line conditioner with fast output voltage control is proposed . The line conditioner is made up of an AC chopper with reversible voltage control and a transformer for series voltage compensation . In the AC chopper , a proper switching operation is achieved without the commutation problem . To absorb energy stored in line stray inductance , a regenerative DC snubber can be utilized which has only one capacitor without discharging resistors or complicated regenerative circuit for snubber energy . Therefore , the proposed AC chopper gives high efficiency and reliability . The output voltage of the line conditioner is controlled using a fast sensing technique of the output voltage . It is also shown via some experimental results that the presented line conditioner gives good dynamic and steady-state performance for high quality of the output voltage
