Abstract
In this paper a low cost topology for compensation of voltage sags and swells is proposed. The dynamic voltage restorer neither uses rectifier stage nor dc capacitor and thyristors can be used as switching devices, resulting in a significant cost reduction. The control system is simple, eliminating the use of powerful computational platforms, causing also a cost reduction and reliability increase. To validate the simulation models, an experimental control platform is used to evaluate the proposed dynamic voltage restorer.
