Abstract
An alternating-current (AC) voltage regulator including an isolated power supply, a control circuit, an amplifier, and an output. The isolated power supply is configured to receive an input voltage and output a direct-current (DC) signal isolated from the input voltage. The control circuit is configured to adjust a portion of the input voltage, and output an adjusted voltage. The amplifier is configured to output a differential signal. The differential signal is based on at least one selected from a group consisting of the isolated DC signal, the adjusted voltage, and a feedback loop. The output is configured to add the differential signal to the input voltage resulting in a regulated voltage, and output the regulated voltage.

An alternating-current (AC) voltage regulator comprising:
- an isolated power supply configured to receive an input voltage and output a direct-current (DC) signal isolated from the input voltage;
- a control circuit configured to adjust a portion of the input voltage, and output an adjusted voltage;
- an amplifier configured to output a differential signal, the differential signal based on at least one selected from a group consisting of the isolated DC signal, the adjusted voltage, and a feedback loop;
- and
- an output configured to add the differential signal to the input voltage resulting in a regulated voltage, and output the regulated voltage.
A method of regulating an alternating-current (AC) voltage, the method comprising:
- receiving, via an isolated power supply, an input voltage;
- outputting, via the isolated power supply, a direct-current (DC) signal isolated from the input voltage;
- adjusting, via the control circuit, at least a portion of the input voltage;
- outputting, via the amplifier, a differential signal, wherein the differential signal is based on at least one selected from a group consisting of the isolated DC signal, the adjusted voltage, and a feedback loop;
- and
- adding the differential signal to the input voltage resulting in a regulated voltage;
- and
- outputting, via the output, the regulated voltage.
