Abstract

In this paper two topologies of a low cost series compensator for voltage sags (SCVS) are introduced. Both topologies deliver to a sensitive load in a distribution system, three-phase sinusoidal balanced and regulated voltages, even under voltage sags. They differ, however, on where the diode rectifier is connected: at the in-bus or at the out-bus (regulated) 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
