Abstract (en)
This document describes an on-load tap-changer device based on solid-state switches for applications that require dynamic voltage regulation. The tap changer of the invention is provided with a central control unit that determines the optimal operating setpoint as a function of the information supplied by the local control units associated with each of the phases. For this purpose, the local control units are linked to a series of voltage and current sensors that determine the operating status of the tap changer. In addition, these local control units actuate the control signals of the solid-state switches to select the optimal tap determined by the central controller.
