DESIGN AN AUTOMATIC VOLTAGE COMPENSATION DEVICE USING AN AC CHOPPER CIRCUIT

Abstract

This paper proposes an automatic voltage regulator (AVR) based on series
voltage compensation mechanism by AC chopper. The proposed AVR consists of a
pulse-width-modulated (PWM) AC chopper and a transformer for series voltage
compensation. The AC chopper circuit provides direct AC power without the need
for an energy storage element, thus reducing the size and cost of the AVR.
Simulation results demonstrate that the proposed AVR responds quickly to
changes in input voltage.
