Abstract
An alternating-current (AC) voltage regulator configured to receive an input voltage. The regulator including an AC/DC pulse-width modulated (PWM) power supply configured to receive the input voltage and output a direct-current (DC) signal isolated from the input voltage. The regulator including a control circuit configured to receive a portion of the input voltage, adjust an amplitude and a phase of the portion of the input voltage, and output the adjusted voltage. The regulator including an amplifier configured to receive, via an power input, the isolated DC signal; receive, via a first input, the adjusted voltage; receive a feedback loop from an amplifier output to a second input; and output, via the amplifier output, a differential signal. The regulator including an output configured to add the differential signal to the input voltage resulting in a regulated voltage, and output the regulated voltage.
