In this paper, the topology of a low cost series compensator for voltage sags (SCVS) are introduced. This device deliver to a sensitive load in a distribution system, three-phase sinusoidal balanced and regulated voltages, even under voltage sags. This topology differs from the typical DVR (dynamic voltage restorer) in the literature, however, on where the diode rectifier is connected: at the in-bus (DVR) or at the out-bus-regulated (proposed topology - IDVR) of the SCVS. In order, to validate the developed SCVS a prototype was implemented verifying the SCVS dynamics in the presence of a voltage dip caused by the turn-on of an inductive load, and harmonics due to the diode rectifier
