Analysis of series compensation and DC-link voltage controls of a transformerless self-charging dynamic voltage restorer

Abstract

This paper describes a transformerless self-charging dynamic voltage restorer (DVR) series compensation device used to mitigate voltage sags. A detailed analysis on the control of the restorer for voltage sag mitigation and dc-link voltage regulation are presented. A nonlinear element is shown to exist in the regulator, the activation of which can adversely… (More)
