AC Voltage Regulation by Switch Mode Buck-Boost Voltage Controller
نویسندگان
چکیده
Voltage sag is a serious power quality problem affecting domestic, industrial and commercial customers. Voltage sags may either decrease or increase in the magnitude of system voltage due to faults or change in loads. In this paper a switch mode AC BuckBoost regulator is proposed to maintain voltage across a medium size domestic appliance constant during long period of voltage deviation from the rated value. Such deviation may occur due to change in load or change in input voltage due to voltage sag of the system itself.
